摘　　要：对3个1/2缩尺钢板墙束柱试件分别进行单调和往复加载拟静力试验,研究其在水平荷载作用下的破坏机理、抗侧刚度、受剪承载力及滞回性能;对钢板墙束柱试件建立有限元分析模型,并按照试验加载制度进行数值模拟分析,得到了钢板墙束柱试件的力学性能;在试验和有限元分析的基础上,提出了钢板墙束柱的抗侧刚度及受剪承载力理论计算式。试验、分析及计算结果表明,单调荷载作用下钢板墙束柱试件抗侧性能稳定,层间位移角达到1/50时,加载后期试件承载力不下降,延性性能好;往复荷载作用下钢板墙束柱试件的滞回性能稳定,层间位移角达到1/50时承载力没有降低,滞回曲线平滑、饱满;钢板墙束柱的抗侧刚度及受剪承载力的理论计算结果与试验及有限元分析结果很接近。This paper studied the capacity, stiffness and hysteretic performance of bound-columns with steel plate shear wall （BC-SPSW）, using static and quasi-static test, finite element method （FEM） as well as theoretical analysis. Results show that the BC-SPSW exhibits a high performance in resisting lateral force. The load bearing capacity does not decrease when the drift ratio reaches to 1/50. When the specimens are under cyclic loading, the hysteretic curves of specimens are well-rounded, implying the stable energy dissipation capacity of BC-SPSW. Also, this paper has proposed design method on stiffness and load bearing capacity of BC-SPSW, based on the deformation and mechanical performance of specimens. Comparative results show that the calculated values of theoretical method are much close to test data and FEM values.
