为研究不同构造条件下混凝土柱-钢梁混合节点的抗震性能，提出一种新型钢筋混凝土柱-钢梁混合结构节点，对其进行了低周往复荷载试验，并与文献已有节点试件的抗震性能进行了对比研究．结果表明：新型节点能获得较高的承载能力；采用削弱外伸梁端节点的构造措施，能将塑性铰从梁端外移，避免对节点核心区的不利影响，实现“强柱弱梁，强节点弱构件”的抗震设计要求；该新型节点滞回曲线整体呈纺锤形，等效粘滞阻尼系数为0.31，表明端板屈曲能较好耗散能量，具有良好的耗能能力．

In order to study the seismic behavior of RC columns-steel beams with different details , a new type of RC columns-steel beam connection was proposed .Through the experimental study on low cycle loading , the seis-mic behavior of the joint was analyzed , and the node was compared with existing joints .The research shows that:the new node can obtain higher bearing capacity;the position of plastic hinge is out-transmitted to the weakening section which may avoid the unfavorable influence of plastic hinge on the joint core by the weakened structural measures of overhanging beam;strong column and weak beam , strong node weak component of the seismic de-sign requirements is realized .The hysteretic curve of the new node is spindle-shaped;equivalent viscous damp-ing coefficient is 0.31 .The buckling end plate can dissipate energy , and it has good energy dissipation capacity .
