Probabilistic Analysis of RC Buildings Based on Incremental Dynamic Analysis

Abstract Earthquake is a natural disaster that can induce immense damage to properties and human lives. Fragility curve, defined as the probability of reaching or exceeding specific state under an earthquake excitation, provides prediction may occur during earthquake. Incremental Dynamic Analysis Curve (IDA curve) developed from analysis be considered initial step fragility curve development. The present study summarises development IDA for RC building considering maximum roof displacement storey drift Damage Measure (DM) peak ground acceleration Intensity (IM). curves using incremental dynamic provide overview exceedance limits in existing when acted upon by different levels excitations performance level improved incorporating appropriate design changes.
