Different displacement ductility demands different ultimate value of axial compression ratio in Shear wall which can calculate by different deformation. Curvature ductility is derived by displacement ductility of shear wal , and ultimate curvature of the wal is calculated by the yield curvature and the curvature ductility. The ultimate compressive strain of concrete which is used in edge components in shear wal is determined according to the relationship of stress-strain of concrete confined by hoop steels. The paper determines the ultimate value of axial compression ratio of shear wal .
