    Abstract:

    One shear wall totally reinforced with steel bars and the other four shear walls partly or totally reinforced by CFRP bars in the longitudinal direction were tested under the reversed cyclic loading. Based on the analysis of the crack width, crack distribution and lateral deformation of the five shear walls, the influence rules of the reinforcement methods of partly or totally reinforced by CFRP bars on the self-centering performance such as residual crack and residual deformation of reinforced concrete shear walls were researched. The results showed that the crack loads of the shear walls with CFRP bars were lower than that of reinforced concrete shear wall. The shear walls with CFRP bars had more cracks and more extensive crack distribution. The maximum crack widths, residual crack widths and residual deformations decreased by 60%, 70%, and 90%, respectively, which indicated the shear walls reinforced by CFRP bars had excellent self-centering performance.
