Abstract：Precast buildings represent an important direction in the development of China′s construction industry and have been greatly developed. Fast construction methods have higher requirements for component installation error control, especially the precision of embedded parts such as steel bars and steel plates. On the other hand, the connection between the precast components is easy to cause the brittle failure mode of the structure node failure. In this paper, a precast concrete shear wall structure with large tolerance is proposed, using section steel to connect the shear wall panels and strengthening the connection with steel to meet the requirement of “strong joints and weak member”. The structure of the precast shear wall is described in detail, and the design method concerning the shear capacity of the connection and the length of the embedded steel is proposed. The parametric analysis is conducted on a typic wall to analyze its seismic behavior. On the basis of model validation, the Abaqus software is used to construct the finite element model of the wall so as to study its seismic performance. And the influence laws of different structural parameters on the seismic performance are concluded. The research results show that the design formula of shear capacity is reasonable. The plastic hinges of the precast shear wall will transfer to the wall panel away from the connection area, realizing the design requir-ement of “strong joints and weak member”. The maximum bearing capacity of the precast member is increased by 15% copared with that of the cast-in-place wall. It is shown that the load bearing capcacity is influenced much by the reinforcement ratios in the edge member, and axial compression ratios, but less by setting a shear steel plate.
