为了给窑尾框架结构节点的设计与分析提供参考,针对实际窑尾钢管混凝土框架梁柱节点在单调加载和低周往复加载下的受力、变形性能进行了研究。采用数值分析方法分析了窑尾结构典型梁柱节点的抗震性能,对节点单调加载下的承载力、低周往复荷载作用下的延性以及耗能能力等指标进行了比较。结果表明,加强环式钢管混凝土节点表现出典型“强柱弱梁”型节点的特征,节点具有良好的滞回耗能能力。 In order to provide reference for the design and analysis of the joint of kiln-end frame structure, the force and deformation performance of the beam-column joints of kiln-end CFST frame under monotonic loading and low-cycle reciprocating loading are studied. The numerical analysis method is used to analyze the seismic behavior of the typical beam - column joints with kiln - tail structures. The monotonic loading of joints, the ductility under low cyclic reciprocating loads and the energy dissipation capacity are compared. The results show that the concrete filled circular CFST joints show typical characteristics of “strong column and weak beam” type nodes, and the nodes have good hysteretic energy dissipation capability.
