Cyclic inertia forces induced by an earthquake motion excessively concentrate on the shear wall as a constituent member of a medium-rise reinforced concrete structure under the influence of it's high initial stiffness. Then, it is reasonably considered that the high overturning moment yielding at the basement may cause the shear wall to rotate with the separation between a footing and the ground surface. And it is also considered that the interactive behavior of the up-lifting shear wall and flexural frames coupled system connected by boundary beams may cause the total behavior to differ from the simple behavior of either an isolated shear wall component or a flexural frame element. Then, in order to discuss the failure mechanism and the particular behavior of apractical reinforced concrete structure with the up-lifting shear wall, a nonlinear seismic response analysis of an idealized multidegrees-of-freedom system was applied to the shear wall-flexural frames coupled system. The transient story stiffness was determined by reducing from the complete structural stiffness of the coupled system. According to the results, the ductility and the seismic performance of the coupled system subjected to an earthquake motion are examined in this paper. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
