摘　　要：为揭示钢筋混凝土框架夹心节点与传统节点抗震性能的差别,对空间中节点、空间端节点和空间角节点3组共6个试件进行对比试验,重点针对受力性能、变形性能、耗能性能以及梁筋粘结锚固性能进行对比分析。结果表明,夹心节点抗震性能稍劣于传统节点,但在保证抗剪承载力等性能的前提下用于工程实践是可行的。In order to know the difference between seismic resistant performance of reinforced concrete beam-column sandwich joints and traditional joints, six specimens of 3 sets, including interior joints, exterior joints and edge joints were tested and compared. Integrated results and behaviors consisting of load resistant capacity, ductility, energy dissipation capacity, beam bar anchorage were investigated. The comparison study showes the aseismie performance of the sandwich joints is not as good as that of traditional joints. But it is feasible to put sandwich joints in practice.
