| Research Abstract |
In this study, RC frames with unreinforced concrete block(CB) wall are experimentally investigated to evaluate their seismic capacity. For this purpose, one-fourth scale, one-bay specimens with/without CB wall are designed, and in-plane loading tests are carried out. In this report, the diagonal strut mechanism of CB wall including its main angle, average compressive strain, central axis, and equivalent width is discussed using principal compressive strains on CB wall. The lateral strength carried by CB wall and RC frame is also explained based on the compressive stress acting on CB wall and the curvature distribution along both columns during the test.
