| 摘 要： | 钢框架节点在低周往复荷载作用下的滞回曲线是评价其抗震性能的重要指标,为了得到中高强度钢材钢框架梁柱组合节点滞回模型,本文通过4个足尺组合节点试件在往复荷栽作用下的破坏试验,获得了节点滞回曲线的骨架曲线和包络图,分析了混凝土楼板配筋率和加裁方式对节点承载和延性的影响,并由此得到考虑组合节点承载能力和刚度退化的三线型恢复力模型.由分析结果可以看出,楼板配筋率主要影响节点延性;正对称加载会明显提高节点的初始刚度和正弯矩极限承载力;恢复力模型可用于弹塑性地震时程反应分析.

| Abstract: | In order to investigate the hysteretic characteristics of beam-to-column composite connections in middle-high strength steel frame,four full-scale composite specimens are subjected to destructive test under the low-cyclic reciprocating load.Then the skeleton and the envelope of hysteretic curve are obtained,and the impact of reinforcement ratio and loading mode on the bearing capacity and ductility of the connection are analyzed.Based on the test results and analysis,the three linear restoring force model o... |
