Abstract

Considering the continuous threat of terrorist attacks on vital structures, it is imperative to enhance their resilience to blast impacts. Current analytical approaches are costly and complex, necessitating a more streamlined method to evaluate structures under such threats. This research addresses this by introducing a machine learning (ML) model that predicts the highly nonlinear behaviour of reinforced concrete (RC) slabs under blast loadings. A database with 936 samples, including both experimental and numerical data, was carefully created for this study. The investigation scrutinized eight ML algorithms, refined them to four based on their performance, and optimized them using grid search, genetic algorithm, and particle swarm optimization (PSO). The gradient boosting-PSO hybrid model emerged to be superior, with a remarkable 91% accuracy in predicting maximum deflection. Further, a comprehensive influence analysis was conducted using the SHapley Additive exPlanations (SHAP) method to understand the contributions of various input parameters, pinpointing scaled distance and panel thickness as critical factors. This study, besides offering a rich database, also serves as an educational tool, shedding light on hyperparameter optimization techniques and SHAP analysis. The research promises a robust and interpretable ML model poised to significantly influence the practical engineering domain in improving the structural design of RC slabs facing blast impacts.

Abstract

Low-Cost Flat Housing is the housing for low income group.. It began with a flat which has two bedrooms in each unit, then it was increased three bedrooms. The three bedrooms flat has to fit the floor area of 650 square feet, in which was later revised to 700 square feet. Small overall floor area which comes with small budget allocated for its construction, could lead to poor indoor environmental quality (IEQ) in low-cost flat, if not properly designed. This paper discusses on the occupants’ satisfaction perception of IEQ of a low cost flat in Kampung Teras Jernang, Selangor. The methodologies used in this study are site observation and questionnaire survey. This study concludes that the IEQ in the selected low-cost flat has acceptably fulfilled the needs and quality required by the occupants. However, there is a factor that the building occupants have expressed poor perception, which is the noise pollution.

Abstract

One of the early objectives of high-density low-cost flat housing is to overcome the squatter problems in urban areas such as in Kuala Lumpur. As the country progresses towards being a developed nation, the quality and standard of living of its people have also improved. Low-cost flat housing initiative has also gone through changes to provide better living quality. This paper discusses on the occupants’ satisfaction perception of outdoor environmental quality (OEQ) of a selected high-density low-cost flat housing located in the state of Selangor in Malaysia. The objective of the paper is to obtain the level of perception by the occupants of low-cost flats on the OEQ. The methodologies used in this study are site observation and questionnaire survey. This study found that the OEQ in the low-cost flat has generally fulfilled the five out of 6 elements of OEQ. The only element that found to have poor perception is the level of safety.
