Abstract: The geological faults, soil amplification, mass, and stiffness of the building governs its seismic performance. The seismic vulnerability of buildings is assessed in this study considering all the above mentioned parameters. The extended finite fault modelling is used to generate ground motions at the engineering bedrock level. Furthermore, the field tests are carried out using multichannel analysis of surface wave (MASW) equipment on soft and medium soil conditions and results are used for the ground response analysis to obtain surface-level ground motions. These motions are used for nonlinear time history analysis of the reinforced concrete buildings with different masonry infill orientations. Finally, the outcome of the analysis is to derive the fragility curves using inter-storey drift (ISD) as damage measure (DM) and peak ground velocity (PGV) as an intensity measure (IM).
