| 摘 要： | 本文主要讨论了外贴FRP加固钢筋混凝土梁的开裂性能,对我国现行钢筋混凝土设计规范GB50010-2002中的裂缝计算公式进行了适当的修正,提出了适用于加固构件的裂缝计算模型,该模型考虑了钢筋—混凝土和FRP—混凝土界面间粘结力的影响。文中对裂缝间距和裂缝宽度的模型预测结果和试验结果进行了比较,对比结果表明文中提出的计算模型是合理的。

| Abstract: | This paper focuses on the cracking analysis of RC beams strengthened with externally bonded fiber rein- forced polymer(FRP)sheets.A semi-empirical calculation model obtained based on the modification to the formula- tions in GB50010-2002 is presented,where both the force transfer of steel-concrete interface and that of FRP-concrete interface.Comparisons between theoretical predictions and experimental results,in terms of crack spacing and crack width,indicate that the proposed model is reasonable. |
