（天津大學(xué)土木工程系 300072）[提要] 通過3根鋼筋混凝土柱在周期反復(fù)荷載作用下受力性能的試驗(yàn)研究，驗(yàn)證了用碳纖維布包裹鋼筋混凝土柱來提高其延性這種補(bǔ)強(qiáng)加固方法的有效性，分析了碳纖維布的包裹范圍、包裹方式等因素對補(bǔ)強(qiáng)加固效果的影響；同時編制了計(jì)算機(jī)全過程受力分析程序，分析了較高軸壓比情況下構(gòu)件延性的變化情況，為進(jìn)一步研究奠定了基礎(chǔ)。
[關(guān)鍵詞] 鋼筋混凝土柱 碳纖維布 延性 抗震性能Based on the experiment of three reinforced concrete columns under cyclic loading, the effectiveness of the new method of using carbon fibre sheet(CFS) on strengthening the reinforced concrete columns for increasing their ductilities is examined and the factors such as wrapping area and wrapping manners are analyzed. At the same time, a computer program is developed to analyze the ductility of the columns under higher axial compression ratio.
Keywords: reinforced concrete columns; carbon fibre sheet; ductility
