The results of experimental tests conducted on the shear walls reinforced by the new method are presented in order to develop the reinforcing method to increase ductility of framed shear walls for which the predominant action is shear. This new method is to confine the potential shear failure regions of edge columns in steel tubes. The experiments conclude that the ductility of the shear walls reinforced by the proposed method is increased remarkably by preventing the shear failure of edge columns completely. This is hard to prevent by conventional methods such as hoops. It is also clarified that the shear strength, deformation and ductility factor of these shear walls are estimated quantitatively by the analysis based on the arch mechanism.
