往复荷载作用下方钢管混凝土柱组合扁梁连接节点滞回性能试验研究
|
摘要
进行了2个方钢管混凝土柱组合扁梁外加环板式节点试件在恒定轴力和水平往复荷载作用下的滞回性能试验,初步了解了该类节点的受力性能和破坏过程,分析了环板宽度对节点抗震性能的影响。结果表明,随着环板宽度的增加,节点的承载能力和刚度都有较大程度的提高;混凝土板的存在对节点性能有一定的影响。
Two specimens of external stiffening ring joints of the composite slim beam to the concrete filled square tube column were experimentally studied on the hysteretic behavior under combined constant axial load and cyclically lateral load.This kind of joint behavior and failure process are obtained preliminarily,and the influence of the stiffening ring width on the joint's seismic resistance is examined.The results show that the load bearing capacity and rigidity of joints increase obviously with the increase of the width of rings;the existence of concrete plate has some influence on joint behavior.
