| 摘 要： | 本文对3个T形钢管混凝土柱与钢梁外伸端板连接节点进行了低周反复荷载作用下的试验研究及分析,研究外伸端板连接节点破坏形式及抗震性能。分析结果表明:该类节点的强度主要取决于高强螺栓的强度及外伸端板的强度和刚度,高强螺栓强度和外伸端板厚度的不同直接影响节点的性能;该类节点具有较好的耗能性能,强度较高。这些研究结果对外伸端板连接节点的研究和应用提供了一定的理论基础。

| Abstract: | This paper presents an experimental study and analysis of three end-plate connections of concrete-filled steel tube T-section column and steel beam under low-cycle repeating horizontal load.The damage form and the seismic performance of end-plate connections is studied.The results of analysis indicate that the strength and rigidity of the joint are mainly determined by the strength of high strength friction grip bolt,and the strength and rigidity of the end-plate.The strength of high strength fiction grip bolt and the thickness of end-plate affect the performance of the joint and the joint has good energy dissipation capacity and high strength.The results provide the theoretical basis for the study and application of end-plate connection joint. |
