Earticle

Large earthquakes had occurred frequently through out the world so that estimating nonlinear seismic response of structure is very important research tasks for seismic design to minimize the demage. The most accurate method for computing nonlinear behavior of structure is nonlinear response history analysis, but it is time-consuming and necessitates more efforts. Therefore, approximate nonlinear methods have been studied to conveniently estimate nonlinear response of structure. Modal pushover analysis among variety of approximate nonlinear methods, based on the assumption that responses of nonlinear system are uncoupled between any mode, combines each nonlinear mode response to evaluate total inelastic behavior. In this study, it is to estimate and compare nonlinear response of structure under earthquake load by both nonlinear response history analysis and modal pushover analysis by using total 60 earthquake records, each 20data of 3 design earthquake levels.
