摘要：

The self-centering structure is a type of new structure that aimed to improve the restorability of structure after earthquake. Through low cyclic loading tests on one cast-in-place RC shear wall and three self-centering RC shear walls, different failure modes of the cast-in-place and the self-centering specimen were studied, and the effect of moment contribution ratio on the seismic performance of the self-centering shear wall was studied. The results indicate that compared with the cast-in-place shear wall, the self-centering specimens are damaged only slightly with small residual deformation and can be easily restored after earthquake. Pinching can be observed obviously in the hysteresis loops of the self-centering specimens, which makes the hysteresis loop flag-shaped. As the moment contribution ratio increases, the self-centering ability is improved, while the energy-dissipating ability decreases. © 2019, Editorial Office of Journal of Building Structures.
