通过3个H型钢粱端板螺栓连接节点的低周往复荷载试验,研究了3种不同梁端构造节点的抗震性能,分析了往复荷载下不同构造节点的破坏形态、滞回曲线、刚度退化、延性等指标.试验结果表明3个节点的滞回曲线饱满,具有较强的耗能能力;梁端局部有约束的节点延性高于其他2个节点;梁端有狗骨型削弱的节点性能与梁端未削弱的节点基本一致;梁端构造不同对节点刚度退化及耗能能力的影响并不显著.%In order to study the seismic behavior of H-shaped steel column and beam with bolted end-plate,three specimens with different beam-end detailing were test subjected to cyclic loading,and the seismic behavior of test specimens was evaluated in terms of failure mode,hysteresis curve,stiffness degradation,ductility,etc.Based on the test result,it could be drawn that the hysteresis curves of three specimens were full,exhibiting good ability of energy dissipation;the ductility of the connection with local confinement at beam end was better than that of others;the seismic behavior of the dog-bone connection was basically consistent with that of normal steel beam-column connection;and the beam-end deta-iling had no significant influence on the stiffness degradation and energy dissipation.
