摘　　要：本文通过低周反复加载试验对2个T形带加劲肋柱贯通式钢管混凝土异形柱与钢梁框架节点进行了试验研究,研究了不同肢高肢厚比情况下节点的滞回性能、强度及延性、破坏特征等特性。试验结果表明,钢管混凝土异形柱与钢梁框架节点滞回环饱满、耗能能力较好,强度和延性较高,抗震性能较好。试验结果能够为这种新型结构形式在实际工程中的应用提供指导意见。In this paper, reinforced concrete filled steel tubular special-shaped column with the two T-shaped stiffening ribs under low cyclic loading tests and steel beam frame shaped nodes were studied. Also, the high limb of different thiekness ratio hysteretic characteristics,strength and ductility,failure characteristics and other characteristics were studied. The results expose that steel concrete column and steel beam frame joints show full hysteretic loops,better energy dissipation,higher strength and ductility,higher seismic performance. The test results are able to provide guidance for this new form structure in the practical engineering application.
