摘　　要：为了解端板厚度对焊接H型PEC柱型钢梁端板连接节点的抗震性能影响,对3个PEC柱型钢梁端板连接节点试件在低周反复水平荷载作用下的滞回性能进行了试验研究.研究了试件的破坏形态,分析得到了焊接H型PEC柱型钢梁端板连接节点的弯矩-转角滞回曲线、骨架曲线、耗能能力、延性、刚度以及破坏模式等.试验结果表明:随着端板厚度的增加,试件的极限转角、耗能能力和延性随之增大.节点的破坏模式有两种,分别为梁端出现塑性铰和端板断裂.For learning the effect of the end plate thickness to seismic behavior of end plate connections in partially encased concrete composite column-steel beam joint,three model specimens under low frequency cyclic pseudo static loading were tested. By observing the failure process of each specimen and analyzing testing data,hysteresis curves,skeleton curves,energy dissipation capacity,ductility,stiffness and failure mode were concluded. The test results show that increasing the thickness of end plate can increase the turn ductility and energy dissipation capacity of nodes. There are two failure modes,which are the plastic hinge of beam and the fracture of end plate.
