Nonlinear Dynamic Analysis

Abstract

To determine the performance of structures facing earthquakes the method which is becoming increasingly significant is nonlinear dynamic analysis. To perform nonlinear dynamic analysis the method used here is incremental dynamic analysis. Range of structural response from elasticity to yielding is being covered and further extended up to dynamic instability. A 10 story reinforced concrete building frame structure was developed. The computational model was analyzed. For simulation software used is Opensees - Open System for Earthquake Engineering Simulations. High Performance Computing facility of C-DAC is used for simulations. The results indicate the probability of yield and collapse of the structure when subjected to a series of earthquakes.
