钢管混凝土隔板贯通式节点的性能

隔板贯通式节点是一种新型钢管混凝土柱-钢梁连接形式。以中海广场为工程背景，进行了钢管混凝土柱一钢梁隔板贯通式节点的拟静力试验，并结合数值模拟结果对该类节点的性能进行了研究。试验结果表明，钢管混凝土柱一钢梁隔板贯通式节点具有较好的刚度、承载能力和延性，能够满足“强柱弱梁，强节点弱构件”的抗震设计原则。数值模拟与试验结果相吻合，可以采用本文所建立的数值模型模拟钢管混凝土柱～钢梁隔板贯通式节点的性能。采用数值的方法，重点研究了隔板尺寸对该结点性能的影响，并提出设计建议。

Analysis on the Behavior of Diaphragm Through Connection between Steel Beam and Concrete-filled Steel Tubular Column

Diaphragm through connection is a new kind of connection between steel beam and concrete-filled steel tubular column. Quasi-static test and numerical simulation had been carried out to investigate the behaviors of diaphragm through connection used in Zhonghai Square. The results show that, the bearing capacity, rigid and ductility of the diaphragm through connection are excellent, and the seismic principle, i. e., ＇strong column but weak beam~ and ＇strong connection but weak componentS, is reached. The numerical model of diaphragm through connection was provided, and the results drawn from the model agreed with the test results, influences of diaphragm dimension on the behaviors of the diaphragm through connection with praposed the numerical model had been investigated, and the design suggestion was provided based on the analysis.
