（天津大學土木工程系 300073）[提要] 對1/2縮尺比例、單層單跨的3榀鋼筋混凝土T形柱斜撐框架和1榀鋼筋混凝土T形柱框架在低周反復水平荷載作用下進行了試驗研究，分析了鋼筋混凝土異形柱斜撐框架的承載力、剛度、延性、恢復力特性、耗能能力及破壞機制等。研究結果表明，鋼筋混凝土T形柱斜撐框架結構具有良好的抗震性能。

It was shown by the cxpcrimcntal rcsults that the carthquake rcsistant bchaviour of R.C. T-shapcd column braccd frame structure is satisfactory.
