The developments of the analytical fragility methods in seismic risk assessment – A review

Abstract

The fragility curves are an essential tool in the seismic assessment of structures and provide a versatile tool to conduct vulnerability analysis for retrofitting and strengthening purposes. The available advancements of computer computational power led to the improvement of the efficiency of the analytical fragility curves. Therefore, this paper focuses on reviewing the recent research developments in the analytical fragility analysis methods. Furthermore, the developments of the intensity and damage measures are presented. In addition, the joint hazards effects on structural fragility are addressed particularly for the environmental degradation and mainshock-aftershock sequence. Finally, recommendations are presented for improving the fragility analysis and highlighting the possible future research areas.

Systematic Mapping of Global Research on Disaster Damage Estimation for Buildings: A Machine Learning-Aided Study

“…Analytical approaches were the most used method to develop fragility curves, followed by empirical approaches. Different numerical methods, simulations, and experimental methods were used to develop analytical damage functions, whereas empirical damage functions were developed based on the observed data [63]. The analytical approach enabled the generation of required data that fulfilled the gaps, such as the absence of actual damage data from disasters [64] and the requirement of damage data from higher-magnitude incidents than those observed.…”
