A dual system of RC structure consisted of moment-resistant open frame and new type of shear wall is proposed by authors. The features of the structural system are to remain the same story drift of each story and to posses the large energy dissipating capacity. The former is owing to the rigid shear wall panels and avoids the crashing of a particular story of the structure. The latter is according to the steel coupling girders which are spanned narrowly between the two rigid shear wall panels and are acting as hysteretic dampers due to their compulsorily large deformations. Tests are carried out on two specimens of one-fourth scaling model. These are the wall parts of one-bay and three-story of the proposed structural system. The results of cyclic lateral loaded tests show large energy absorbing capacities without strength deteriorating manners until the fracture of coupling girders occurs.
