Incremental Dynamic Analysis and Seismic Fragility Analysis of Reinforced Concrete Frame

Abstract Due to technological developments in last decade, new methods of seismic evaluation are use like simulation based, algorithm probabilistic, software based etc. These have enabled researchers move from linear non-linear analysis. Incremental dynamic analysis (IDA) is performance method where a suite ground motions applied structure further scaled particular levels intensity. Seismic fragility curves become significant estimation structures risk possibility the point view potential earthquakes and helps predicting economic consequences for forthcoming earthquakes. The paper reflects IDA storey + 7 floor (G 7) reinforced concrete frame subjected eleven motions. Primary objective was perform equivalent static linear-dynamic meet National International codal requirements. Then, pushover carried out by introducing parametric auto hinges as per ASCE 41-13 tables. To carry analysis, both geometric material non-linearity introduced. Strong were selected suitable criteria then SeismoStruct 2022 using curves, out. results study found useful predict probability damage under
