（同濟(jì)大學(xué) 上海 200092）[提要] 通過對鋼筋混凝土圓柱模型纏繞碳纖維布的軸心受壓試驗(yàn)研究，詳細(xì)介紹了用碳纖維布加固后的圓柱破壞特征，其受力性能及破壞機(jī)理，碳纖維布約束混凝土與鋼筋及鋼管約束混凝土的差異。并提出了用碳纖維加固鋼筋混凝土柱的軸心受壓承載力計算方法。
[關(guān)鍵詞] 碳纖維 碳纖維布 構(gòu)件加固 鋼筋混凝土柱 軸心受壓A test of concrete circular-columns wrapped with carbon fiber fabric under axial compression is presented. The performing characteristic and confinement mechanism of CFRP-wrapped columns are demonstrated in details. A satisfying theoretical model is suggested to predict the ultimate strength of CFRP-wrapped circular-columns under axial compression.
Keywords: carbon fiber reinforced plastics(CFRP); strengthening;concrete column; axial compression
