In this study, a shear test was performed on the joints of an existing brick building constructed in Meiji period. The distribution of joint mixing proportion, width of joint, filling ratio, and distribution of porous, which are thought to affect shear strength, were analyzed. The possibility of influence of these factors on shear strength was clarified. Based on the knowledge obtained from these studies, points to be noted when evaluating the shear strength of joints in existing brick buildings were clarified.
