摘　　要：为解决三边连接屈曲约束钢板墙在自由边两个角部首先发生破坏的问题,文中提出了一种新型三边连接K形屈曲约束钢板墙。采用ABAQUS有限元软件对三边连接矩形和K形屈曲约束钢板墙进行受力性能分析,获得了屈曲约束钢板墙的屈服荷载、初始刚度、荷载位移曲线、塑性应变分布和屈服区分布。结果表明K形屈曲约束钢板墙的屈服荷载、初始刚度以及荷载位移曲线与矩形屈曲约束钢板墙相差不大,但在延性和耗能能力方面表现更佳。最后,提出了形式简洁计算精度较高的该类新型屈曲约束钢板墙的理论计算公式,可为K形屈曲约束钢板墙的工程设计提供参考。In order to prevent the early failure at the corners near the free side of three-side connected buckling restrained steel plate shear wall(TBRW),a novel K-shape buckling restrained steel plate shear wall with three-side connection(TBRW-K) is proposed in this paper.The yield capacity,initial stiffness,load-displacement curve,plastic strain distribution,and yielding region distribution are obtained according to the mechanical performance analysis of TBRW and TBRW-K by using ABAQUS finite element software.The analysis results show that the yield capacity,initial stiffness,and load-displacement curve of TBRW-K are almost the same to that of TBRW,but the TBRW-K has better ductility and energy dissipation capacity than that of TBRW.Finally,simple theoretical calculation formulas with high precision are presented for the engineering design of TBRW-K.
