【摘要】 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.更多还原

【Abstract】 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.更多还原
