矩形钢管混凝土柱-H型钢梁隔板贯通式节点试验研究

         

摘要

Two full-scale concrete-filled rectangular tube column-to-H beam connections with different connection details were tested under cyclic loading. Behavior of test specimens was evaluated in terms of failure mode, hysteresis curve, and ductility. Test results showed that both specimens performed in a ductile manner with plastic hinges formed in the beam end near the column face, and exhibited a strong column-weak beam failure mechanism. The hysteresis curves of both connections were full and showed good energy dissipation. The connection details have significant effect on the ductility of connections.%开展了2个构造不同的矩形钢管混凝土柱-H型钢梁隔板贯通式节点试验,重点研究了低周反复荷载下节点的滞回曲线、破坏形态、位移延性等指标.结果表明2个节点的破坏形态均为梁端形成塑性铰;实现了“强柱弱梁”、“强节点弱构件”的设计目标;2个节点的滞回曲线均呈梭形,表现出较好的耗能性能;节点构造对其位移延性影响显著.
