As part of the development of a European Seismic Risk Model 2020 (ESRM20), the spatial and temporal evolution of seismic design across Europe has been studied in order to better classify reinforced concrete buildings (which represent more than 30% of the approximately 145million residential, commercial and industrial buildings in Europe) and map them to vulnerability models based on simulated seismic design. This paper summarises the model that has been developed to assign the years when different seismic design levels (low code, moderate code and high code) were introduced in a number of European countries and the associated lateral forces that were specified spatially within each country for the low and moderate codes for typical reinforced concrete mid-rise buildings. This process has led to an improved understanding of how design regulations evolved across Europe and how this has impacted the vulnerability of the European residential building stock. The model estimates that ~ 60% of the reinforced concrete buildings in Europe have been seismically designed, and of those buildings ~ 60% have been designed to low code, ~ 25% to moderate code and 15% to high code. This seismic design model aims at being a dynamic source of information that will be continuously updated with additional feedback from local experts and datasets. To this end, all of the data has been made openly available as shapefiles on a GitLab repository.

This public report provides an overview of the problems raised by the management of heritage buildings and sites (HBs/sites) in their surroundings. A multidisciplinary team comprising conservation professionals, art historians, archaeologists, architects, biologists, civil engineers and information technology experts have joined forces within the framework of the European Cooperation in Science and Technology1 Action TD1406 - i2MHB (Innovation in Intelligent Management of Heritage Buildings) to provide their expertise and experience on the risks to which HBs/ sites are exposed (urban development, infrastructure works, demographical changes, natural and technological hazards, bio-deterioration, lack of cultural heritage education and technical knowledge and skills, etc.). Traditional and new approaches to manage the principal risks are then developed. Nine representative European HBs/sites are used to illustrate the different problems raised and to offer possible solutions. The report ends with a number of recommendations to better integrate HBs/sites in their surroundings. This report is addressed to policy makers at the local, regional and national governments; economical and industrial players; research and education stakeholders; and, the public to the preservation and valorisation of HBs/sites in their surroundings. We hope that readers will find tentative answers to their question(s) on the difficulties encountered by the management of HBs/sites in their surroundings. Further reading is available through the references and the online literature provided.
