Prabhakaran , S. Anand Kumar , Sophia Immanuel , Mohd. Saqlain, K. Puja The response of an existing structure when subjected to seismic excitation can be evaluated its performance and safety. There are different elastic & inelastic approaches to analyse a structure using Equivalent Static Analysis, Linear dynamic analysis, Nonlinear Static Analysis, Nonlinear dynamic analysis. In equivalent static analysis method or linear static analysis, the stiffness of the structure remains constant whereas in Nonlinear Analysis, the stiffness of the structure varies and the total force is plotted against a reference displacement to obtain a capacity curve. In nonlinear dynamic analyses, the detailed structural model subjected to a ground-motion provides estimates of t deformations at each degree of freedom in the model. A numerical simulation is carried out to evaluate the seismic performance of a 3-storey already existing state library in Andaman & Nicobar Island. As Andaman & Nicobar Island is located in soft to medium soils, response of the building is analyzed under a simulated earthquake ground motion at Andaman & Nicobar Island site is compared with that under a measured earthquake ground motion of EI-Centro. In this paper, a comparative study of seismic response of a library building modeled as both bare frame and frame with infill is analyzed by the linear analysis, pushover and time history analysis has been performed using SAP 2000 v18 software as per the IS- 1893-2016-Part-1.
