Abstract

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+17 storey building and is about 78 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 45 earthquakes in 3 sets of hazard levels (2%, 5%, and 10% Probability of Exceedance [PE]) to generate the inter-story drift values. Based on the Performance-based approach given by FEMA 356, the Fragility curves are developed by creating the Probabilistic Seismic Design Modal. The resultant fragility curves are given in terms of 3 probabilities i.e., (1) Immediate Occupancy, (2) Life Safety, and (3) 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
