%X 提出一种带自复位耗能支撑的钢板剪力墙(SPSW-SCEDB), 由墙板与自复位耗能支撑组成, 对其构造及工作原理进行了介绍．对SPSW-SCEDB在低周往复荷载作用下的滞回性能进行数值模拟, 并与两边连接钢板剪力墙进行对比分析．结果表明, SPSW-SCEDB滞回曲线呈旗形, 具备良好的承载能力、耗能能力与复位能力．与两边连接钢板剪力墙相比, SPSW-SCEDB极限承载力提高31% , 残余变形角减小91% ; 同时, 由于支撑与墙板的共同作用减缓了承载力退化, 改善了延性及耗能能力, 验证了SPSW-SCEDB具有良好的抗震性能．<br>A kind of steel plate shear wall with self-centering energy dissipation brace(SPSW-SCEDB)is proposed，which is composed of steel plate and self-centering energy dissipation braces. Configuration and working principle of SPSW-SCEDB are introduced. Hysteretic behavior of SPSW-SCEDB is simulated under low cyclic reversed loadings，and then compared with that of steel plate shear wall with two-side connections. Results indicate that the SPSW-SCEDB exhibits flag-shaped hysteretic performance，and has good bearing capacity，energy dissipation capacity and self-centering capability. Compared with the steel plate shear wall with two-side connections，the ultimate bearing capacity of SPSW-SCEDB is increased by 31% ，and the residual drift ratio is reduced by 91% . Meanwhile，the interaction between braces and steel plate slows down the bearing capacity degradation and improves the ductility and energy dissipation capabilities. It is verified that the SPSW-SCEDB has good seismic performance
