In recent strong earthquakes, Hyogoken-Nanbu Earthquake suggested the difficulty of realization of Weak-Beam Type R/C Structures and the existence of quite a few Weak-Column Type R/C Structures. And now, R/C Structures will be required to evaluate performance, for example, maximum deformation. Generally, maximum deformation of R/C Structure is calculated by the dynamic response analysis of MDOF or Multi-story frame. But it is not easy. On the other hand, there are previous studies to estimate the maximum deformation by SDOF without dynamic response analysis. Though, there are few simple methods to estimate the maximum deformation of R/C Structure with collapse story by using SDOF. The purpose of this study is, as a former stage of estimating collapse story's maximum deformation in MDOF without response analysis, to investigate the correlation of collapse story in MDOF with equivalent SDOF. As a result, it is shown that time-history response deformation of both collapse story in MDOF and equivalent SDOF approximately correspond. In maximum deformation, these system's correlation is changed by instantaneous input energy. Then it is shown the possibility of simple estimation of collapse story's maximum deformation.
