Estimating nonlinear seismic response of structure is very important research tasks in the context of earthquake engineering, and it is necessary for performance-based seismic design. 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. Uncoupled 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 uncoupled pushover analysis, and look over characteristics and reliability of nonlinear seismic response using uncoupled pushover analysis.
