The seismic performance of the precast shear wall was improved by using a newly developed reinforced tenon to strengthen the precast joint, which is used to bear the shear force of the precast joint and reduce the effect of dowel action on the vertical connecting steel bars. The vertical connecting steel bars were only used to bear tensile and compressive stress and consume seismic energy. The seismic performance of reinforced tenon precast shear wall was investigated by quasi-static tests on one reinforced tenon precast shear wall specimen and one ordinary flat seam precast shear wall specimen. This study investigated the crack distribution and failure modes, precast joint slip of the two specimens, and the seismic performance parameters such as bearing capacity, stiffness degradation, ductility performance and energy dissipation capacity. The test results demonstrated that the reinforced tenon effectively reduced the slip of the joint surface and exhibited good ductility and energy dissipation capacity than that of the ordinary flat seam specimen, while the failure mode, bearing capacity, and stiffness were similar to that of the flat seam specimen.
