Abstract: In order to restore the injured shear wall after earthquake, and make the previously built shear wall meet the requirements of new revised anti-seismic specifications, the strengthening methods for shear wall are proposed. Strengthening the shear wall by applying angle steel is one kind of these methods. The bearing capacity, hysteretic curve and other parameters of the strengthened shear wall are compared with those without strengthened by experimentation. The results indicates that the reinforcement of the limb base of shear wall by using angle steel is really an ideal method. And the study can provide reference for similar strengthening projects.
