［提要］  結合工程實踐，進行了三個不同形式的后包鋼管混凝土框架節(jié)點和一個普通鋼管混凝土框架節(jié)點的低周反復加載試驗。研究后包鋼管混凝土框架節(jié)點承載能力和抗震性能，以及不同鋼管厚度、不同加勁肋形式對節(jié)點承載能力和抗震性能的影響。試驗結果表明，后包鋼管混凝土框架節(jié)點的抗震性能不低于普通的鋼管混凝土框架節(jié)點。研究為加固鋼筋混凝土柱提出了一種新方法。

Abstract:Tests for three different kinds of steel beamRC column postcovered with steel tube frame joints and one concrete filled steel tube frame joint are carried out, and the effect of tube width and the stiffening rib on the behavior of bearing capacity and seismic performance have been studied. The test results show that the bearing capacity and performance of steel beamRC column covered steel tube joints is not lower than that of the common concrete filled steel tube frame joint.
