摘　　要：对施加预紧力的端板螺栓连接波浪腹板钢梁-高强箍筋约束混凝土柱节点抗震性能进行研究。设计2组共4个足尺节点试验模型,进行低周反复加载拟静力试验。通过观测节点模型的受力、变形、破坏过程及破坏形态,分析其承载能力、变形能力和耗能能力,验证了新型节点的可靠性。结果表明：在梁端加劲板作用下,波浪腹板钢梁端塑性铰外移并发挥其耗能能力;研究结果为该新型节点的工程应用提供可靠的理论依据。The seismic performance of end plate bolt connection wave beam web-high-strength stirrup constraints of concrete column nodes was studied. Two sets of four full-scale nodes were designed and pseudo-static experiments were carried out under low reversed cyclic loading. By observing the stress,deformation,failure process and failure pattern of the node model,the bearing capacity,deformation capacity and energy dissipation capacity were analyzed,the reliability of the new node was verified. The results show that under the function of beam end stiffening plate,the plastic hinge of wave beam web moves outboard to exert its energy dissipation capacity,which can provide reliable theoretical basis for engineering application of the new node.
