Seismic behavior of earthquake-damaged pre-cast shear wall specimen with full scale strengthened by enlarging cross-section method was studied in this paper,so as to provide references for the engineering field. Earthquake-damaged pre-cast shear wall were tested under cyclic loading. In this loading system,force and displacement control were used. The experimental results showthat after reasonable and reliable reinforcement,the failure modes of the wall was compression and bending failure;the pre-cast shear wall had a improvement effect on increasing the ultimate bearing capacity after strengthened,while maintaining good ductile deformation and energy dissipation ability. The study indicated that the seismic performance of rehabilitated pre-cast shear wall before seismic damage under a certain damage level. Enlarging cross-section is very effective seismic strengthening method for pre-cast shear wall.
