内置钢板梁墙节点抗震性能试验研究

Experimental research on seismic behavior of beam-wall joints with built-in steel plate

为考察分析连梁中配置钢板的梁墙节点的受力性能,对3种形式的9个梁墙节点试件进行了梁端低周往复荷载作用下的拟静力试验研究,分析了各试件的承载力、耗能能力、滞回特性及节点域变形等。结果表明:增加内置钢板的厚度可以提高梁墙节点的承载力,但对梁墙节点的延性影响不大;内置钢板上满布栓钉的梁墙节点在延性和承载力方面均优于内置钢板锚固区布置栓钉的梁墙节点。

In order to investigate and analyze the mechanical performance of beam-wall joints with built-in steel plate,9specimens of beam-wall joint designed in three different types were studied through the pseudo-static tests at beam end under low cyclic loading. The loading capacity,dissipation capacity,hysteretic characteristics and deformability of joint core area and so on were analyzed. The results show that increasing thickness of the built-in steel plate can improve the bearing capacity of beam-wall joint,but make little impact on the ductility. The ductility and the bearing capacity of the beam-wall joints with the stud arrangement on all the built-in steel plate are better than that with the stud arrangement on the anchorage zone of built-in steel plate.
