To study the seismic performance of precast shear walls, in which the vertical rebar is connected by a new type of hybrid connection (the vertical steel bars in the edge members are connected by composite straight-thread sleeve and the vertical distributed steel bars are connected by anchoring closed loop reinforcement) and the surface of the precast shear wall is full-length shear resistant groove, quasi-static tests of two precast reinforced concrete shear walls and a cast-in-place reinforced concrete wall were carried out. The shear span ratio of the specimens was 1.91, which was designed according to strong shear weak bending. Results show that the failure mode of the precast shear wall was normal section compression failure, which was consistent with the design. There were no visible cracks in the sleeve and no slip of the connecting steel bar at the end of the test. The seismic performance of the precast wall specimens was basically the same as that of the cast-in-place wall specimen, which meets the requirements of the current code. The normal section compressive bearing capacity of the precast wall specimens was not less than 1.1 times the calculated value of that of the cast-in-place wall specimen, and thus the current specification formula can be used to calculate the normal section compressive bearing capacity of precast shear walls. When the inter-story drift ratio was 1/100, the deformation of the precast wall specimens was basically the same as that of the cast-in-place wall specimen, and the vertical deformation of the section basically agreed with the plane section assumption. There was no obvious slip of the horizontal surface and vertical surface and no obvious opening of the vertical surface, indicating good integrity between the precast and post-cast parts of the wall.
