Special Issue Information

Dear Colleagues,

The frequency of natural disasters and the rise in global terrorist incidents underscore the urgency of enhancing the safety of building structures and critical infrastructure across their lifecycle. These entities now confront multifaceted challenges posed by a spectrum of hazards, encompassing earthquakes, explosions, fires, impacts, and more. Structures subjected to unforeseen loads often experience progressive or disproportionate collapse, characterized by the nature of "low probability, high consequence", leading to significant societal impacts. As socioeconomic progress continues, structural design has evolved from a single, overarching goal of "ensuring life safety" to specific, multifaceted performance objectives. This shift highlights the pressing need to ensure the comprehensive defensive performance of building structures under the threat of multiple hazards.

The aim of this Special Issue is to collect results and to promote discussion and developments from recent research pertaining to the performance analysis, assessment, design, and reinforcement of structures subjected to multiple hazards. This encompasses analyses for structures' resistance against progressive collapse, seismic events, fire incidents, impact scenarios, as well as enhancements in the performance of both new and existing structures. Please feel free to contact us if you require further clarifications regarding this Special Issue.

Due to their roles as efficient lateral force-resisting systems, reinforced concrete shear walls exert a tremendous degree of influence on the overall seismic performance of buildings. The ability to predict the boundary transverse reinforcement of shear walls is critical to the seismic design process, as well as in the overall evaluation and retrofitting of existing buildings. Contemporary empirical models attain low predictive accuracy, with an inability to capture nonlinearity between boundary transverse reinforcement and different influencing variables. This study proposes a boundary transverse reinforcement prediction model for shear walls with boundary elements based on the demand of ductility. Using the extreme gradient boosting machine learning algorithm and 501 samples, some 52 input variables are considered, and a subset with six features is selected, monitored, and analyzed using both internal methods (gain and cover) and external methods. The results (R2=0.884) display superior predictive capacity compared with existing models. Interpretation and error analysis are performed. Safety analysis is conducted to obtain references for use in practical engineering. Overall, this study presents a more accurate tool for use in seismic design and provides references for the evaluation and retrofitting of existing buildings. Our contributions hold significant implications for enhancing the safety and resilience of reinforced concrete structures. Full article
