Fragility curves for steel–concrete composite shear wall building with torsional irregularity
Abstract In this study, building model which is trapezoidal in plan with steel–concrete composite shear walls (SCCMSWs) is reduced to 1/4th scale in order to validate modal information and joint responses analytical results with AZALEE shake table under the scope of the SMART program. Incremental dynamic analysis (IDA) is performed on numerical model, and the maximum inter-storey drift is determined as a response parameter for all simulations. Fourteen real ground motion records are used to study the ground motion variability. Further, seismic fragility curves are developed based on IDA results to assess uncertainties in hazard evaluation of structure. Damage probability matrices under various damage states obtained from fragility curves are compared for building as per pre-established damage indicators of SMART 2008 and HAZUS 2003 specifications. It is concluded that, SCCMSWs building structure considered in the study behaves well when subjected to severe earthquakes.
