This article adopts two methods for repairing earthquake damaged shear walls, namely, replacing damaged concrete with high-strength grouting material and planting reinforcement to increase the section and wrapping it with steel mesh.

These methods are convenient to construct and cost-effective Through quasi-static tests and finite element analysis, the seismic performance parameters of precast shear walls with different methods of repairing seismic damage were obtained.

The main conclusions are as follows:.
