In the near future, the building sector will continue to absorb the greatest share of primary energy worldwide. It is necessary to find innovative solutions that promote energy efficiency through renovation measures, especially in historical buildings, for which refurbishment is constrained by several issues. In this study, we propose a novel Trombe Wall configuration that is easily integrable and based on a rock wall made of caged stone to use as a thermal accumulator. The system was investigated preliminarily using a transient Finite Difference Method (FDM) code to analyse the temperature field inside the rock wall. Successively, FDM results were employed as input data in TRNSYS simulations to determine the savings achievable in thermal heating requirements. The results demonstrated that the proposed solution, in the considered climate and on a reference historic building, can produce monthly heating savings varying between 26% and 85%. So, the rock wall results in a reliable solution for buildings in which refurbishment is difficult, allowing for preserving aesthetic features and improving energy efficiency by rationally using solar radiation.

Nowadays, as the changes in social conditions and requirements occur, it is seen the transformations in the requirements of buildings and spaces. The effort in regaining historical buildings to life is an important universal aspect to dwell on for cities. When the historical city buildings lose their functions in spite of their well existences structurally, they can be usable for the adaptive reuse according to conditions of current life requirements with their suitable characteristics instead of leaving them to destroy. In this research, it is evaluated the adaptive reuse of the historical buildings for high educational purposes. In this aspect the Faculties of Architecture of the Universities Kadir Has, Bilgi, Mardin Artuklu and Toros are chosen as the examples for the adaptive reuse of the historical buildings for educational purposes as faculties of architecture. Faculties' design studios and classrooms' conveniences after adaptive use are examined in the qualitative aspects of their functions, materials, structures, infrastructures, installations, lightings, architectural styles.

Abstract The daylighting feature of historical buildings can be accepted as an intangible heritage since it contributes to the unique atmosphere of the buildings. However, with the change of the built environment and the change of the historical building itself, the level of daylight intake of historical buildings changes. This study contributes to the field by revealing the daylighting performance changes of a historical khan building which has a unique architectural characteristics. The changes in the daylighting levels of Buyuk Yeni Khan, one of the largest historical khans in Istanbul, are examined through its modifications. Using 3D Lidar scanning technology, the current state of the khan is scanned. The daylight intake and glare analyzes of the khan for its current and original states are made through simulations, and the values found are compared. DA, cDA, UDI, sDA and DGP metrics are used in the simulations. As a result, due to the changes such as enlargements along the arcades, additional overhangs and the change of window ratios of the facades of the rooms on the ground floor, the rooms of the khan have different daylighting values compared to its original state.

Abstract Historical buildings carry the key technologies and practical values throughout the development of architectural heritage. Investigating the restoration techniques for historical buildings under various forms of damage is an essential step in the conservation and utilization of these structures. Utilizing Web of Science (WOS) and China National Knowledge Infrastructure (CNKI) as the primary databases, this study employs the PRISMA methodology to search and screen relevant research literature. A comprehensive review of the retained literature is conducted, analyzing publication trends, co-citation networks of authors and keywords, among other characteristics. To enhance the visibility of restoration techniques, three-dimensional modeling diagrams are created using actual case information of material or component damage as a reference, thereby increasing the referential value of the review content on historical building restoration techniques. The study provides a thorough review of over 30 restoration techniques corresponding to 9 types of damage from the perspectives of historical building walls and wooden components. Additionally, new materials or technologies mentioned in the retrieved literature are categorized; for instance, in the context of moisture-proof treatment for brick masonry, traditional methods are explained, and new research on electrochemical desalination and lipid-based waterproof materials is discussed and evaluated. Finally, given the multifaceted value and the variable mechanisms of damage in historical buildings, an analysis of the restoration process and techniques reveals that the restoration of historical buildings is a complex interdisciplinary process. The development and implementation of restoration plans should adhere to the principles of cultural relic protection to ensure their reasonableness and effectiveness, while also considering sustainability and environmental adaptability to protect and reuse historical buildings, thus leveraging their cultural and historical values. Moreover, the advancement of restoration techniques for historical buildings in the future should be based on the inheritance of traditional craftsmanship and materials, while also integrating new technologies, materials, and concepts to enhance the applicability and efficiency of traditional techniques.

Introduction. The study was carried out to determine the possible causes of damage to the finishing plaster coverings on the facades of historical stone buildings, built in St. Petersburg before 1917, as a result of their humidification and subsequent frost destruction.Materials and methods. The mechanism of humidification of a homogeneous wall structure plastered on both sides due to the moisture transfer from the room to the environment through the wall thickness due to the difference in partial pressures of water vapour from inside and outside the room during the cold season is studied. The paper provides the graphs of the distribution of the actual and maximum partial pressures of water vapour over the thickness of the wall structure, depending on the type of plaster covering, for two calculated cases — for the conditions of the coldest month and the coldest five-day period in St. Petersburg.Results. It is revealed that for the conditions of the coldest month in St. Petersburg, the actual partial pressure of water vapour in the thickness of the wall structure under consideration does not exceed the maximum, which indicates the absence of conditions for moisture condensation in the thickness of the wall envelope. However, as the vapour permeability of the external plaster decreases, the curves of the distribution of the actual and maximum partial pressures converge at the interface of the stone base and the plaster covering. For the conditions of the coldest five-day period, the actual partial pressure of water vapour already at a distance of 135 mm from the inner surface exceeds the maximum partial pressure, which indicates a high risk of moisture condensation, and this risk is the higher the less vapour permeable the plaster covering is.Conclusions. It is proven that when the coldest outdoor temperatures are established, there is a high probability of condensation of water vapour in the thickness of the wall structure under consideration. The highest risk of freezing of the condensable moisture will be observed at the interface of stone base with the external plaster. Freezing of moisture in cracks and voids in the contact zone of the stone base and the plaster covering can lead to water trapping, the occurrence of significant internal stresses in the finishing layer and, as a result, to its gradual damage, up to the loss of individual fragments of plaster.

Background: The strength of historical buildings built in different centuries with various materials and construction techniques and harboring many structural problems depends on the structural system, geometrical condition, and material properties. Sungurlu clock tower, whose system and geometry are in good condition, has been damaged under environmental and climatic effects, earthquakes, and other loads, and has survived to the present day by preserving its structural integrity to a great extent with the repairs it has undergone. Methods: In addition to static analysis, the robustness and durability of the design of the tower were tested by dynamic analysis with the SAP2000 program. In the model that will represent the actual system behavior of the tower, the lengths of the elements; nodal points; bearings; joints; shapes such as bars, shells, and plates; characteristic values of the materials to be used; as well as the system, element sections, and all loads and combinations of masses or dynamic forces acting on the system are defined. Results: In the reports presented visually, the moment, shear force, axial forces, and other forces to which the tower was exposed after the architectural and structural problems were eliminated were seen in a diagram. Since the effects of the damage could not be predicted, in this study, to measure the reaction of the building against earthquakes and other loads, the numerical model representing its original condition was prepared and analyzed according to the theoretical method and assumptions made by the restitution, survey, and static observation reports. Conclusions: With this program, which allows for the preparation of this model, it was concluded that the loads coming to the structure according to the principles of ductility, rigidity, and strength could be safely transferred to the ground without causing damage to the structural system and its elements. From the deformation, stress, velocity, acceleration, and reaction force graphs obtained, it was understood that the tower exhibited the expected structural behavior under its own weight and live loads. The stress and reaction force graphs showed that the structural materials are adequate for the resistance of the structure and system against the existing loads and possible earthquakes.

Chinese universities have gone through three periods of centralized construction and significant differences in the design of teaching buildings in different periods may cause various thermal environment problems. This study takes a city in a cold region in northern China as an example and selects three teaching buildings built during three concentrated construction periods: 1950s to 1960s, 1980s to 1990s, and early 21st century as common cases. Based on field research, thermal environment measurement, APMV and PMV-PPD evaluation, and DeST simulation methods, it was found that the average summer APMV of the three teaching buildings was 1.37, indicating poor thermal comfort. In winter, the ambient temperature of the classrooms was below 18 °C for about 30% to 40% of the whole year, the average PMV value was −2.36, and the PPD value was obtained as 83.28%, far exceeding the standard requirements. The obtained results form a design strategy to optimize the thermal environment of teaching buildings. By considering the teaching building of historical architecture from the 1950s to 1960s as an example, the optimization design was carried out from three aspects to improve the indoor thermal environment and reduce the building's cooling and heating load. The cumulative load of the building throughout the year was reduced by 21%, the cumulative heat load was reduced by 28.3%, and the cumulative cooling load was reduced by 10.1%. This research is anticipated to be of great reference significance for enhancing the thermal comfort of existing buildings, promoting energy conservation, and reducing carbon emissions. At the same time, it contributes to the protection and optimal use of historical buildings. [ABSTRACT FROM AUTHOR]

Strong winds or typhoon disasters pose significant risks to historical buildings in many countries and regions. Although numerous researchers have discussed the damage caused by natural wind disasters, little attention has been paid to the potential impact of renovation and adaptive reuse strategies on the wind resistance performance of historical buildings—an avoidable human-induced factor. This study selected the representative ancestral hall building in Guangzhou, namely Lujiang Academy, for on-site investigation and Computational Fluid Dynamics (CFD) simulation analysis. It examined two renovation approaches: installing glass curtain walls around the courtyard and enclosing the top of the courtyard with a glass canopy. This study also assessed the roof wind pressure distribution in its unaltered state to evaluate the impact of different renovation strategies on roof wind load distribution. The results showed that installing glass curtain walls can effectively reduce the upward suction effect on the main hall roof, thereby improving its wind resistance performance. Conversely, enclosing the courtyard with a glass canopy may increase negative pressure on areas such as the eaves and corridor roofs, raising the risk of roof damage. This study systematically evaluated the renovation strategies for historical buildings, detailing the specific impacts of different retrofit measures on the wind resistance performance of building roofs. The methods and findings are significant not only for the renovation of ancestral hall heritage buildings in Guangzhou but also for providing practical scientific methods and technical strategies for the conservation and renovation of similar historical structures. This research demonstrates an effective approach to enhancing wind resistance and preventive protection for historical buildings. [ABSTRACT FROM AUTHOR]

The article presents the results of the preliminary experimental research and analysis of the structure of samples of clay solid bricks from six historical buildings erected in Poland in the years 1300 to 1910. Images obtained with a scanning electron microscope; parameters characterizing the pore space of the ceramic material, which were obtained using mercury porosimetry; and chemical composition identified using an energy dispersive X-ray spectroscopy, were analyzed. The test results showed that as the age of the brick increases, the homogeneity of its structure decreases, the chemical composition of all samples is quite similar, and in the tested samples, large disproportions in the percentage of pore width in individual ranges can be observed. An indicator P-index useful in comparing the studied structures was proposed, based on the knowledge of the share of the pores' width within the adopted ranges. [ABSTRACT FROM AUTHOR]

The construction industry of Ukraine shall not only recover but also upgrade, enhance and reevaluate existing building projects. Further research raises two pertinent issues for Ukraine - retrofitting and reconstructing destroyed infrastructure. The study's priority objective is to restore damaged and ruined buildings rapidly. It may be achieved using the creation of recovery methods in Ukraine and countries in the post-conflict stage of development. The research involves creating technical specifications for the product of a new version of the automated construction management system, which provides working with the software complexes based on the BIM model. The system implies using Building Information Modeling (BIM) and Artificial Intelligence of Things (AIoT) to make organization of reconstruction faster, better and less costly. The research has been held to demonstrate the viability of the approach. In addition, we acquire a reduction of energy consumption and an increase in the lifespan of the building by choosing retrofitting methods. The efficacy of BIM and IoT technologies enables the integration of contemporary demands to diminish design time and costs. These technologies also optimise design solutions by assimilating knowledge from previous building and structure designs. Additionally, they offer essential information support for the entire investment project life cycle. [ABSTRACT FROM AUTHOR]

Abstract The city centre of Khiva (Uzbekistan), called Itchan Kala, is an architectural complex included in the UNESCO list of tangible cultural heritage. One of the historic buildings in it is the Juma Mosque. It has a simple rectangular structure, but is very large and has 213 deeply carved wooden columns supporting the roof. The article presents the process, problems, and their solutions resulting from the implementation of 3D laser scanning of such highly detailed and geometrically complex historical architectural objects in the conditions of normal tourist traffic. The optimisation of scanning positions, scanning in situ implementation, as well as the processing of the acquired data and the construction of a 3D mesh model of the mosque interior are presented. It is pointed out that scanning such objects with high accuracy and density of measurement points causes major technical problems related to the workload, and the huge volume of data acquired and processed. The possibilities of making the 3D model available in digital space for the purpose of researching the appearance and geometry of the mosque, its individual columns, as well as popularising the monument are also discussed. It is highly probable that the scanning of the Juma Mosque's interior presented here was carried out for the first time in history.

Determining the seismic performance level of shaft structures is crucial due to their vital role in ensuring a water supply. Since these are underground structures, the loads they encounter and the structural modeling processes differ significantly from those of above-ground structures. Accordingly, the primary aim of this paper is to introduce a new modeling methodology for the seismic performance assessment of shaft structures, considering all relevant parameters. This unique approach also incorporates pertinent sections from various applicable local seismic codes. For this purpose, a total of 15 shaft structures located on the historic Atik Valide Waterway, constructed in 1583, were examined. To create numerical models of the shafts, soil exploration parameters were utilized, and the shaft surface-soil interaction was represented by nonlinear p-y springs. An integral part of the presented methodology involved segmenting the shafts at regular intervals, with each segment defined as a separate story. The analysis results demonstrated that the modeling methodology is accurate and aligns well with the observed conditions of the shafts. Considering the significant risk of extensive damage to sewerage systems in urban areas due to soil liquefaction during seismic events, this study is anticipated to serve as a valuable reference in the literature by introducing a new, accurate methodology for identifying potential seismic risks.

Optimal sensor placement for timber architecture heritage poses a significant challenge due to the unique structural types and complex monitoring purposes. In this study, a three-stage method is proposed, taking a courtyard-style heritage, built 133 years ago, as an example. First, a finite element model that accounted for the parameter randomness and initial damage was constructed using a genetic algorithm (GA) and experimental results. Second, a new weighted fitness function of logarithmic type was developed for multi-type sensors and multi-objective monitoring. Third, a novel genetic algorithm, Meta-GA, was proposed, introducing competition group mechanisms and gene libraries to improve optimal capability while maintaining computational efficiency. The Meta-GA is then compared to the other two optimization modes using seven indexes. Finally, damage detection capability was tested for the proposed three schemes at noise levels of 0%, 5%, and 10%. The results reveal that the proposed three-stage method with Meta-GA can provide the best solution. [ABSTRACT FROM AUTHOR]

The changes that occur in the urban patterns of historical monuments over time negatively affect the sustainable development of the city. In the study, the urban pattern analysis of the Greek city of Komotini was made by dividing it into regions, and the change in the urban pattern development of historical monuments was questioned. The city of Komotini joined the Ottoman administration in 1391, the Bulgarian administration in 1913, and the Greek administration in 1920. The city of Komotini has a historical pattern that stands out with its different administrations and has experienced different social patterns. Sustainability of the urban fabric is possible by ensuring urban development with the preservation of historical buildings. In this study, the city of Komotini and its historical buildings were analysed. The change that historical monuments underwent in the urban patterns over time was transferred to a table systematic and determined as the final product. Ensuring the sustainability of historical buildings by protecting them is important to preserving urban memory. By preserving historical buildings and transferring them to future generations, the sustainable patterns of cities would be changed. [ABSTRACT FROM AUTHOR]

Chiaia station is one of the art stations of Line 6 of the Naples underground network; it was constructed in a 50-m-deep excavation, a few meters from historic buildings and 4.5 m from the main façade of a sixteenth-century Basilica. The excavation, carried out partially in loose to medium dense sands overlying the soft rock formation of Neapolitan Yellow Tuff (NYT), was supported by a retaining wall made of contiguous bored piles braced with internal struts and prestressed ground anchors. The excavation sequence was quite complex due to archeological findings and to the presence of anthropic cavities used over the centuries to quarry NYT blocks. One of the key goals of the design was to limit movements around the shaft to prevent damage in the historical buildings. Long-term monitoring data obtained during nearly 9 years confirm the success of the overall construction process. A rather complex three-dimensional (3D) finite-element model with constitutive relationships for both the upper sandy layers and the soft rock is presented in the paper; this model was adopted to back-analyze the data from the monitoring and explore the influence of some of the key features of the case study. The role of the building bending and shear stiffness, of the soft rock stiffness, and of further apparently minor issues—such as the seepage and the ground anchors' prestress—were investigated and discussed with the support of the model calculations. Observed settlements at the end of the excavation were in the range 10–15 mm, and in the long term they increased by 20%–50% to as much as 20 mm. The deflection ratios were very small, in the range 0.05‰–0.15‰ , and no visible damages to the buildings were recorded. These values were reproduced by the finite-element model only after the introduction of the relevant building stiffness. [ABSTRACT FROM AUTHOR]

As a result of the military operations taking place on the territory of Ukraine, thousands of buildings and structures have suffered significant damage and destruction. A substantial share of such buildings belongs to immovable cultural heritage sites, such as historical buildings of local and national significance; frequently, including educational institutions such as kindergartens, schools, lyceums etc. Damaged buildings are subject to restoration by repairing or strengthening their building structures, restoration, or conservation. There is a large number of repair materials and technologies for conducting restoration works, which are regulated by the requirements of DSTU B V.3.1-2:2016. However, while performing repair work on the structures of historical buildings, it is necessary to focus on the DSTU-NB B B.3.2-4 requirements. Among the most common types of damage to historical buildings caused by blast waves, splinters etc., are cracks in the masonry of wall structures and foundations; cracks in the joint of structures; knocking out fragments of masonry with damage to facing; damage to the elements of the floor and covering; systematic soaking of foundations etc. An essential aspect of restoring historical buildings is the maximum preservation of their historical and cultural significance with minimal interventions in the structure of structures and their appearance. The article considers modern methods of restoring the operational suitability of historical building elements, namely repair of cracks by injection and impregnation; strengthening the walls of buildings with the help of external reinforcement with carbon tapes and installation of high-strength rods in stone walls; restoration of stonework using special mixtures; strengthening of reinforced concrete and metal span elements with high-strength carbon fabrics, or lamellas (FRP); installation of waterproofing of walls subjected to systematic locking from the middle of the building.

Historical buildings need to be preserved, shedding light on the history and culture of societies that have survived from the past to the present. These buildings may face the threat of extinction for various reasons. It is important to minimize these threats and transfer the building to future generations healthily. In this regard, traditional techniques or current technologies come to the fore. This study aims to investigate the use of "seismic control methods" in historical buildings, which have emerged as an important method of earthquake conservation in recent years. This study consists of two stages. In the first stage of the study, the legislation related to the conservation of cultural heritage was examined and the important parameters related to the consolidation and restoration of historical buildings were determined. Then, "seismic control methods" related to the strengthening of historical buildings against disasters were examined and the use of these methods in historical buildings was evaluated in terms of international legislation. In the second part of the study, fieldwork was carried out. 3 historical masonry buildings in the Palu district of Elazığ were selected as the study area. These historical masonry buildings are Palu Grand Mosque, Historical Palu Bridge and Cemsit Bey Kulliye. The applicability of seismic control methods in these historical buildings has been investigated in terms of legislation. In the evaluation stage of the study, to minimize the disaster risk of these historical buildings, other examples in the literature were examined and seismic control methods that can be used in historical buildings were determined. As a result of the study, it has been seen that seismic strengthening can be applied using seismic control systems in different historical buildings in Elazığ Palu in accordance with international legislation.

This paper aims to raise awareness of how design methods can significantly influence the visual perception and contextual relationship of contemporary extensions and historical buildings. This study focuses on assessing the design elements that affect visual perception and contextual relationship in 15 contemporary extensions designed by different architects. First, the authors reviewed the literature on restoration, conservation and contemporary extensions, and then generated a questionnaire. The authors surveyed 223 respondents. A mixed qualitative and quantitative evaluation model was established. SPSS was used to evaluate and analyze the 15 selected contemporary extensions and 223 survey samples. The results indicated that contemporary extensions are considered successful when designed using a method compatible with the historical buildings in congruence with related literature and hypothesis. For the buildings examined within this research, no examples were found that copied historical buildings within the scope of visual perception. Despite rich variety, contemporary extensions have been rarely investigated within the scope of visual perception and context relationship. This paper is among the few works that investigate contemporary extensions using approaches of visual perception and context relationship. [ABSTRACT FROM AUTHOR]

Successively, FDM results were employed as input data in TRNSYS simulations to determine the savings achievable in thermal heating requirements. The results demonstrated that the proposed solution, in the considered climate and on a reference historic building, can produce monthly heating savings varying between 26% and 85%. So, the rock wall results in a reliable solution for buildings in which refurbishment is difficult, allowing for preserving aesthetic features and improving energy efficiency by rationally using solar radiation.

Addressing the limitations of current digital simulations for historical buildings, this paper suggests a specific technical task for the development of a simulation analysis platform based on City Intelligent Modelling (CIM). The objective is to establish a systematic approach for digitally maintaining and managing historical dwellings. The technique presented in this paper focuses on constructing sophisticated parametric models that offer numerous modelling benefits, allowing for convenient updates to the Historic Building Information Modelling (HBIM). The text discusses various applications and integrations of Building Information Modelling (BIM) in urban planning, construction projects, and historic building renovations. CIM is presented as a comprehensive digital platform that visually represents cities, aiding urban planners in decision-making for sustainable development. The text delves into the use of advanced analytical tools within CIM for diverse data analysis, predictive modelling, and simulation to forecast trends. The focus shifts to the evolution of BIM, progressing from 3D to 5D models, influencing construction project management and cost estimation. The integration of BIM in historic building projects is explored, emphasising the challenges and proposing innovative solutions using HBIM. The paper also introduces the concept of Infrastructural Building Information Modelling (InfraBIM) in construction management, incorporating Virtual and Augmented Reality for enhanced visualisation.

Grave structures are architectural works reflecting the cultural accumulation, continuity and political power of societies. In the context of sustainability, while "green building" certification systems are developing in building productions in the world, new guidelines are also being created. Of course, new guidelines are also being developed on the certification as green buildings within the scope of the protection and restoration of historical buildings that should be specially considered. In this study, it is aimed to create a model that will allow the historical buildings in Turkey to be evaluated in the context of “the green building” concept. With this model, it is considered that historical building conservation practices will contribute positively to the works of restorers in making those heritage sites more environmentally friendly and sustainable. For the model designed to evaluate historical buildings within the scope of green buildings, historical buildings were handled under 3 groups: a) 1st Group Historical Buildings, b) 2nd Group Historical Buildings and c) Reconstructed Historical Buildings. As creating the designed model, GBC-Italy system criteria were taken as the basis. The criteria were carried out by conducting a questionnaire with experts in this field. Importance of the relevant evaluation criteria in the scoring system were determined by using the AHP method. As a result of the analyzes and calculations, the accuracy of the scoring was confirmed. As historical buildings are evaluated according to the conditions of their periods, it is obvious that they are sustainable buildings. Naturally, nowadays to be able to preserve historical buildings for the future generations in a proper way is usually ensured by giving them a new function. The requirements of the new functions given to create the necessary equipment to provide today's comfort conditions in historical buildings naturally change the sustainable characteristics of the historical heritage. This evaluation system, designed to preserve the green building characteristics of historical buildings and to ensure their sustainability with their new functions, will be an important guide.

Restoration works in historical buildings, which have gained importance in Türkiye in recent years, have unique risks in terms of occupational safety. Employees in this sector are exposed to many different risks during the restoration of historical building projects, and ensuring occupational safety is an important problem for the sector. In order to find a solution to this problem, a comprehensive examination of historical building projects was made in terms of occupational safety during the restoration process. Within the scope of the study every stage of the three different restoration projects was examined in terms of occupational safety. In line with this research, job safety analysis was performed by dividing the steps in the restoration projects into groups. The risks in the construction sites were determined and precautions were presented to eliminate or reduce these risks. As a result, the risks that may occur during the restoration phase of a historical building are shown in detail together with the prevention methods. It is expected that if the stakeholders of restoration projects integrate the information presented into their occupational health and safety systems, it will contribute to the improvement in the processes and there will be a decrease in the frequency of work accidents.

Many historic buildings have symmetry in their geometric configuration. The objective of this research is to denote the application of numerical-vector succession in the structural analysis of historical masonry buildings, with arches and symmetrical systems, including mathematical processes in ancient graphic analysis, emphasizing the importance of loads in the structural stability. We based the analysis on three fundamental stages: recognition of the construction system of the heritage object, geometric discretization of the system and vector analysis under different physical considerations. Hence, the thrust lines are affected by the loads, boundary conditions and history of structural behaviour. Numerical and computational tools offer faster and more accurate graphic analysis processes. Many historic buildings have symmetry in their geometric configuration.

Ancient masonry constructions and historical buildings, such as cathedrals, are exposed to considerable risks attributed to factors like ageing and long-term exposure to both dynamic and static variations in loading conditions. In this study, an innovative and promising monitoring approach was applied to assess the structural integrity of the vault in the central nave of the Turin Cathedral. Specifically, the outcomes obtained from Acoustic Emissions (AE) are correlated with the insights derived from the Thrust Network Analysis (TNA) conducted on the structure. This analysis considers the structural elements introduced early in the twentieth century to mitigate horizontal forces. Acoustic Emission (AE) is a commonly employed technique in structural monitoring to detect and analyze elastic waves generated by crack formation, providing valuable information about structural damage. The Thrust Network Analysis (TNA) is an approach that applies Heyman's principles to represent stress in masonry vaults. This method models the stresses as a discrete network of forces, achieving equilibrium with gravitational loads. In this context, the results obtained by TNA analysis are strictly correlated with AE localization results.

Addressing the limitations of current digital simulations for historical buildings, this paper suggests a specific technical task for the development of a simulation analysis platform based on City Intelligent Modelling (CIM). The objective is to establish a systematic approach for digitally maintaining and managing historical dwellings. The technique presented in this paper focuses on constructing sophisticated parametric models that offer numerous modelling benefits, allowing for convenient updates to the Historic Building Information Modelling (HBIM). The text discusses various applications and integrations of Building Information Modelling (BIM) in urban planning, construction projects, and historic building renovations. CIM is presented as a comprehensive digital platform that visually represents cities, aiding urban planners in decision-making for sustainable development. The text delves into the use of advanced analytical tools within CIM for diverse data analysis, predictive modelling, and simulation to forecast trends. The focus shifts to the evolution of BIM, progressing from 3D to 5D models, influencing construction project management and cost estimation. The integration of BIM in historic building projects is explored, emphasising the challenges and proposing innovative solutions using HBIM. The paper also introduces the concept of Infrastructural Building Information Modelling (InfraBIM) in construction management, incorporating Virtual and Augmented Reality for enhanced visualisation.

Background: The strength of historical buildings built in different centuries with various materials and construction techniques and harboring many structural problems depends on the structural system, geometrical condition, and material properties. Sungurlu clock tower, whose system and geometry are in good condition, has been damaged under environmental and climatic effects, earthquakes, and other loads, and has survived to the present day by preserving its structural integrity to a great extent with the repairs it has undergone. Methods: In addition to static analysis, the robustness and durability of the design of the tower were tested by dynamic analysis with the SAP2000 program. In the model that will represent the actual system behavior of the tower, the lengths of the elements; nodal points; bearings; joints; shapes such as bars, shells, and plates; characteristic values of the materials to be used; as well as the system, element sections, and all loads and combinations of masses or dynamic forces acting on the system are defined. Results: In the reports presented visually, the moment, shear force, axial forces, and other forces to which the tower was exposed after the architectural and structural problems were eliminated were seen in a diagram. Since the effects of the damage could not be predicted, in this study, to measure the reaction of the building against earthquakes and other loads, the numerical model representing its original condition was prepared and analyzed according to the theoretical method and assumptions made by the restitution, survey, and static observation reports. Conclusions: With this program, which allows for the preparation of this model, it was concluded that the loads coming to the structure according to the principles of ductility, rigidity, and strength could be safely transferred to the ground without causing damage to the structural system and its elements. From the deformation, stress, velocity, acceleration, and reaction force graphs obtained, it was understood that the tower exhibited the expected structural behavior under its own weight and live loads. The stress and reaction force graphs showed that the structural materials are adequate for the resistance of the structure and system against the existing loads and possible earthquakes.
