The authors have been developing a new structural wall with damage control capacities which include clack-preventing and self-centering for multi-stories buildings in seismic area. When reinforced concrete structural walls failed in large-scale earthquakes,the walls were damaged with apparent clacks. In order to prevent its severe cracks,we proposed to make slits laterally at both sides of lower end of the wall,and conducted cyclic loading tests of the walls. Although the load-deformation relations were obtained as the typical flexural-failure,the appearances of the specimens did not have significant cracks after the tests. The lateral slits at the bottom of the structural wall decreases its flexural c apacity and lateral stiffness to keep no clacks on the surface of the wall after cyclic loading. The maximum strengths are discussed from the points of views of flexural and shearing capacities of the ten test specimens which were already reported on our previous papers. The strengths are estimated by full plastic bendingmoments of the section of the end of the structural wall without considering the strength deterioration by shearing force. The clack-preventing capacity shown by the test results of our proposed wall gives the advantage to the design against shearing force effectively.
