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。研究结果对今后碳纤维布在混凝土结构加固中应用的研究与设计有指导意义
In order to study the effect of CFRP on the stiffness of CFRP reinforced beam, the stiffness of CFRP-reinforced concrete beam is theoretically analyzed first, then the formula of deflection after reinforcement is deduced, and then the formula is tested. The test results of CFRP reinforced beam through 13 different reinforced forms show that the formula has certain accuracy. The research results are of guiding significance for the future research and design of carbon fiber cloth used in the reinforcement of concrete structures
