This research presents a probabilistic seismic responses analysis of high-rise reinforced concrete (RC) buildings using fragility assessment method. Three RC buildings, having the same plan dimension and height (12 story each) but different in structural configurations, were designed and their seismic responses were compared. First building is a Moment Resisting Frame (MRF), second is a MRF with exterior shear walls, and the third building consists most shear walls. Buildings were designed for high-seismic activity zone (i.e. Los Anglos) using the Equivalent Lateral Force (ELF) for seismic loading calculation. Sixteen real ground motion pairs were selected and scaled, then applied orthogonally to the buildings to perform the Incremental Dynamic Analysis (IDA). Fragility curves were developed based on the IDA results for the three limit states including slight damage, moderate damage, and collapse to show the probabilistic comparison of seismic responses among the three buildings in both x and y-directions. It was observed from the fragility assessment results that generally shear walls improve buildings’ seismic performance. However shear wall configuration also affects the seismic performance which needs further study.
