Mullion-type walls, which are separated from columns and are treated as nonstructural elements in general. jointed to RC frame as bending members may raise horizontal load-carrying capacity. However there is probability that the Mullion-type wall's axial elongation has a bad influence on behavior of RC frame. In this paper, one eighth scale two story and three storv specimens were made and tested. Those consist of I span RC frame and the Mullion-type walls at every story. The conclusions are as follows. The Mullion-tvpe wall elongates axiallv in each story, and the upper beams 3re forcibly and more conspicuously deformed by the accumulation of the walls' elongation. Consequently the rotation angle of the upper beams is about one and a half times as large as the drift angle. Experimental horizontal load-carrying capacity correspond to value caluculated as the elongation produces plastic hinge in beams. These verification indicates that the Mullion-tvpe wall joined to RC frame raises horizontal load-carrvmg capacity unless the elogation causes brittle failure of beams.
