In this study, in order to evaluate the effect of retrofitting by CF sheet for the usual vertical joints between precast concrete wall panels, the shear test was carried out using the S-type specimens, which cracked in diagonal direction before the retrofitting. As the test result, it was confirmed that the maximum joint shear strength of the specimens retrofitting by CF Sheet increased and the stiffness of the specimens was same as that of the specimens without damage. From discussion of the test results, it could be considered that the increment of shear strength was the contribution of CF sheet against friction and shear action of joint, and the contribution of CF sheet was evaluated based on the previous formulas for vertical joint of precast reinforced concrete structures.
