摘要:
收集了国内外76根碳纤维增强复合材料(CFRP)加固钢筋混凝土梁试件,针对不同的粘贴方式,分别进行美国规范、欧洲规范和中国规范共3种规范的计算值与试验值的对比分析.结果表明:对侧面粘贴情况,欧洲规范的设计计算公式的预测结果较好;对U形粘贴情况,中国规范的设计计算公式的预测结果较不可靠;对封闭包裹情况,3种加固规范的计算结果均与实验值吻合较好,而中国规范的精度最高.各规范的计算结果存在差异,不同规范的CFRP的有效应变取值不同.
Abstract:
The experimental results of 76 beams reinforced with externally bonded CFRP of three different wrapped models were collected. The comparison between the calculation results by American, European and Chinese codes, and experimental results, show that: for side-bonded CFRP, the prediction of European design standard is accurate; for U-jackets, the prediction of Chinese design code is less reliable; for the fully wrapped CFRP, the predictions of these three models, especially Chinese model, are in good agreement with the experimental values. The different predictions are mainly due to the different methods to calculate the CFRP effective strain values in different codes.
