Abstract


Objective: The objective of this paper is to assess the capacity and performance of the RC frame structure in different seismic zones of India through Incremental Dynamic Analysis. This study utilizes Incremental Dynamic Analysis (IDA) for capacity assessment of the RC frame structure in different seismic zones of India. Method of Analysis: A set of ground motion records is selected and scaled from low seismic intensity to high seismic intensity with site compatible response spectra. The nonlinear time history is applied to structure from lower demand to the demand up to which the structure is failing. Findings: This parametric study involves safety consideration of RC frames with variation in demand. The behavior and performance level of the structure in different seismicity have been studied. The results have been compared on basis of base shear versus roof displacement graph, inter-storey drift ratio and the hinge formation mechanism. Application/ Improvement: The study will illustrate the behavior of the structure for seismic actions and the performance and damages to structure will be acquired. The results will show the proper response of the structure under different seismic loads.
