A self-centering shear wall (SC-SW) with a steel brace-assembled bottom is proposed to avoid the residual drift of reinforced concrete shear walls (RCSWs) due to damage in corners and achieve an adequate earthquake-resilience. The residual displacement of traditional RCSW is caused by the bending and shear deformations of the plastic hinge and the deformation of the upper plate, as is confirmed by a cyclic loading test on a typical RCSW specimen. A steel brace-assembled bottom consisting of a steel V-shaped connecting beam, a bearing, and two self-centering braces is designed to control the residual deformation of the RCSW plastic hinge zone. The simplified equations governing the skeleton curve of the SC-SW are derived. An RCSW and SC-SW with the same initial stiffness and ultimate bearing capacity are simulated and compared via the experimentally validated finite element model. The results indicate that the SC-SW exhibits a flag-shaped hysteresis response with an excellent self-centering capability. The maximum residual story drift ratio is less than 0.125%. The skeleton curve equations agree well with the measured data of the analytical specimen. The overall performance of the SC-SW is primarily affected by the braces. The energy dissipation capability of the SC-SW remains insufficient due to the lesser development of plastic deformation.

为了避免钢筋混凝土剪力墙（RCSWs）由于角落损坏而产生的残余漂移，并实现足够的抗震能力，提出了一种带有钢支撑组装底部的自定心剪力墙（SC-SW）。传统 RCSW 的残余位移是由塑性铰的弯曲和剪切变形以及上板的变形引起的，这通过对典型 RCSW 试样的循环加载试验得到证实。由钢V形连接梁、支座和两个自定心支撑组成的钢支撑组装底部设计用于控制RCSW塑性铰区的残余变形。导出了控制 SC-SW 骨架曲线的简化方程。通过实验验证的有限元模型对具有相同初始刚度和极限承载力的 RCSW 和 SC-SW 进行了模拟和比较。结果表明，SC-SW 表现出旗形滞后响应，具有出色的自定心能力。最大残层漂移率小于0.125%。骨架曲线方程与分析试样的测量数据吻合良好。SC-SW 的整体性能主要受牙套的影响。由于塑性变形的发展较少，SC-SW 的能量耗散能力仍然不足。骨架曲线方程与分析试样的测量数据吻合良好。SC-SW 的整体性能主要受牙套的影响。由于塑性变形的发展较少，SC-SW 的能量耗散能力仍然不足。骨架曲线方程与分析试样的测量数据吻合良好。SC-SW 的整体性能主要受牙套的影响。由于塑性变形的发展较少，SC-SW 的能量耗散能力仍然不足。
