摘要
为研究碳纤维布对 CFRP加固梁刚度的影响 ,首先从理论上对碳纤维布加固后的混凝土梁的刚度进行了分析 ,推导出加固后的挠度计算公式 ,然后通过试验对该公式进行检验。通过 1 3根不同加固形式的CFRP加固梁的试验结果表明 ,该公式具有一定的精确度。
In order to investigate the beam strong degree influenced by the carbon fiber reinforced polymer, firstly, Concrete beam reinforced by CFRP is researched in this character, which educes the flinch formula of the reinforced beam, and then validates the accuracy of the formula by the result of the examination of thirty Concrete beam reinforced differently by CFRP. The results of the investigation have a great guiding significance in the application of the reinforce concert.
