Seismic Vulnerability Studies of a G+۱۷ storey building in Abu Dhabi - UAE using Fragility Curves

The growth of tall buildings in the United Arab Emirates (UAE) has paved the way for a surge in interest in the country's seismic vulnerability investigation. The case study building comprises of shear walls and RC columns as its lateral force-resisting system. It is a newly constructed G+۱۷ storey building and is about ۷۸ meters high. The non-linear dynamic seismic analysis which is the time history modal analysis, also known as Fast Non-linear analysis was performed on the study building with about ۴۵ earthquakes in ۳ sets of hazard levels (۲%, ۵%, and ۱۰% Probability of Exceedance [PE]) to generate the inter-story drift values. Based on the Performance-based approach given by FEMA ۳۵۶, the Fragility curves are developed by creating the Probabilistic Seismic Design Modal. The resultant fragility curves are given in terms of ۳ probabilities i.e., (۱) Immediate Occupancy, (۲) Life Safety, and (۳) Collapse Prevention. The whole study depends on the idea that comparative sort of structures will have a similar likelihood of a given harm state for a given seismic force
