Abstract

The aim of the study is to develop the fragility curves for low-rise, mid-rise, and high-rise concrete moment resisting framebuildings. The concrete moment resisting frame buildings were designed as per Indian seismic design code. The slab elements were modelled as membrane type, shell type and their influence on the probability of damage states obtained from fragility curves is also studied. For the development of the fragility curves, guidelines provided by HAZUS-MH MR4 technical manual has been used. For the analysis, concrete moment resisting frames weremodeled using ETABS. The nonlinear behavior has been incorporated using default plastic hinges in accordance with ASCE 41-13. Spectral demand and spectral capacity curves obtained from the nonlinear static pushover analysis are used for plotting fragility curves. Fragility curves were developed keeping spectral displacement as ground motion parameters
