[提要] 列舉了國內(nèi)外有關(guān)設(shè)計(jì)標(biāo)準(zhǔn)、指南和文獻(xiàn)中的7種CFRP布加固鋼筋混凝土柱受剪承載力的計(jì)算方法，對國內(nèi)外33根柱的試驗(yàn)結(jié)果進(jìn)行了驗(yàn)算，分析了各建議公式計(jì)算結(jié)果的可靠性和CFRP布對受剪的貢獻(xiàn)，在此基礎(chǔ)上提出了實(shí)用計(jì)算建議，供編制有關(guān)設(shè)計(jì)規(guī)范和工程設(shè)計(jì)參考。
[關(guān)鍵詞] 碳纖維增強(qiáng)復(fù)合材料 鋼筋混凝土柱 受剪承載力 纖維有效應(yīng)變The shear strength calculating methods of RC columns strengthened with CFRP sheets, suggested in seven literatures of design standards, specifications and references, are summarized for comparison with the results of 33 tests. The reliability of the seven calculating methods and the shear contribution provided by the CFRP are analyzed. Based on the comparison with experimental results and the analysis,a practical calculating formula to determine the shear contribution of CFRP with enough reliability and simple calculation is put forward. The suggested calculating method can be referred for editing specification and used for construction design.
