摘　　要：对4个钢筋混凝土框架异型边节点试件进行了拟静力试验,以研究此类节点的抗震性能。根据试验结果,总结了异型边节点的破坏形态,研究了节点滞回曲线的特征,讨论了节点核芯配箍率、梁柱截面高度变化对异型边节点抗剪性能的影响,分析了异型边节点的受力机理,提出应以"小核芯"为分析单元来研究此类节点抗裂和承载力的建议,为异型节点设计公式的建立提供了基础数据。For studying seismic behavior of the abnormal exterior joint of reinforced concrete frame, four abnormal exterior joints are tested by the pseudo-static experiment. Based on the experiment results, the damage form of abnormal exterior joint are summarized, characteristics of hysteresis curve are studied, the effect of stirrup ratio and height of column section and beam section on anti-shear property of abnormal joint are discussed, working mechanism of abnormal exterior joint is researched, the conclusion that the anti-crack and bearing capacity of abnormal joint are studied by analyzing the minor core of abnormal exterior joint is proposed, the basic data is provided for the design formula of abnormal joints.
