A precast reinforced concrete shear wall has discrete joint at vertical and horizontal joints between the wall panel and the surrounding frame. The sliding displacement in joints by which precast shear wall display a resistance mechanism differed from that of cast-in place shear wall is expected to occur. From the above points, precast reinforced concrete unit walls are analyzed by substitution method of braces considering the behavious of joints. The joint is replaced by the normal and tangential springs with respect of joint surface. This paper consists of the analysis of model speciments to verify the appropriateness of the assummed characteristics of joints and the analysis of full-scale shear walls to make clear the effect of joint on behavior of the realistic shear walls.
