【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。
[Abstract]:Three specimens with 1 / 2 scale steel plate wall bundles were subjected to pseudostatic tests under monotonic and reciprocating loading respectively, and the failure mechanism, lateral stiffness, shear capacity and hysteretic behavior of the specimens under horizontal load were studied. The finite element analysis model is established for the steel plate wall bundle column specimen, and the mechanical properties of the steel plate wall bundle column specimen are obtained by numerical simulation according to the experimental loading system, and based on the test and finite element analysis, the mechanical properties of the steel plate wall bundle column specimen are obtained. A theoretical formula for the lateral stiffness and shear bearing capacity of steel plate wall bundles is presented. The results of test, analysis and calculation show that the lateral resistance of steel plate wall bundles is stable under monotone load, and the interstory displacement angle reaches 1 / 50. Under reciprocating load, the hysteretic behavior of steel plate wall and column specimens is stable, the bearing capacity does not decrease when the interstory displacement angle reaches 1 / 50, and the hysteretic curve is smooth and full. The theoretical calculation results of lateral stiffness and shear bearing capacity of steel plate wall bundles are very close to the results of test and finite element analysis.
