The purpose of this study is to investigate the input earthquake energy and the maximum story drift in the hybrid structures based on nonlinear time history analysis. The hybrid structures are composed of different restoring force characteristic components, steel moment frames and light gauge steel house shear walls. In the structure having an origin progress slip hysteresis response, the earthquake input energy and the maximum story drift showed an inversely proportional relationship between f value of the input ground motion. Although the hysteresis responses of the structures are different, the earthquake input energy to the structure have a trend to be determined by the f value of the input ground motion and the maximum story drift of the structure. It mentions that earthquake input energy is influenced significantly by the design base shear ratio. Accordingly, the structure with small ductility reduction factor should have large ultimate strength. The structural response of the hybrid structure, steel moment frame was built in to the light gauge steel house shear wall building, improves the seismic performance by the nature of steel moment frame hysteresis response.
