本文通过对较高轴压比和低周反复荷载下的3个钢筋混凝土分体柱框架梁柱中节点和1个对比整截面柱框架梁柱中节点试件的试验研究，分析了节点核芯区的开裂荷载、最大承载能力、破坏形态及其滞回特性等抗震性能；研究了节点上下层柱的分体形式和分体柱过渡区的设置对节点核芯区抗震性能的影响；并给出了分体柱框架梁柱节点的设计建议。
In this paper, the test results of the joint specimens of 3 reinforced concrete beam columns with columnar columns and 1 sectioned full-section column beam with high axial compression ratio and low cyclic loading were analyzed. The cracking load , Maximum load bearing capacity, failure mode and its hysteretic behavior. The influence of the split form of upper and lower pillars and the transition zone of split pillars on the seismic performance of the core region of node were studied. Design Proposals for Beam - Column Joints of Column Frames.
