锚定式方钢管混凝土柱与钢梁节点抗震性能试验研究
|
摘要
通过低周反复加载试验对6个锚定式方钢管混凝土柱-H形钢梁节点进行了试验研究,研究了不同轴压比情况下节点的破坏模式、延性、耗能性能、强度及刚度退化等。试验结果表明,破坏之前节点具有良好的滞回性能、延性及耗能能力,满足现行抗震规范的要求。锚定式方钢管混凝土梁柱节点可以用于拉力较小的节点。文中提出了有关的设计建议。
A total of 6 connections with anchorages for concrete filled square steel tubes with different axial compression force ratios have been tested under low-cyclic reversed loading at the end of column to research the failure modes,ductility,energy dissipation capacity and degradations of strength and stiffness.The experimental results demonstrate that all the specimens have well hysteretic behavior,ductility and energy dissipation capacity before failure.And this kind of joint meets the requirements of the current code for seismic design of buildings.The beam-to-column connection with anchorages for concrete filled square steel tube can be used for connections with minor tension.Additional seismic design recommendations are presented.
