The primary objects of this investigation are to establish numerical values of the surrounding frame froces of reinforced concrete walls after cracks. The cracked zone of wall panel of which principal axis incline to horizontal and vertical axis at forty-five degrees is replaced with orthogonal anisotropic elastic panel. The cracked zone of wall panel is assumed to be one surrounded by crack lines starting at two diagonal corner points of wall panel with the slope of forty-five degrees. The analysis are performed finite element method and its calculation, by Facome 270-20/30. As the result of this study the ratio of the restrain reactions of frame to the average shear stress of wall panel of reinforced concrete walls after cracks are estimate. Furthermore the calculation method of girder stress of reinforced concrete walls after cracks using the above restraint reactions are proposed.
