在合理评定碳纤维布有关力学指标的基础上 ,进行了碳纤维布约束混凝土的受压性能试验。根据试验研究了碳纤维布使用量对普通混凝土抗压强度和变形性能的影响。试验研究发现 :试件包裹碳纤维布后可以提高混凝土的抗压强度 ,并可有效地改善混凝土的变形性能 ,其效果随碳纤维布用量的增加而增大 ;在碳纤维布用量相同的情况下 ,分条包裹的效果要优于整条包裹的效果 ,即碳纤维布在实际工程应用中有个利用效率的问题。将碳纤维布用量折换成等效箍筋用量 ,同时根据理论分析和试验结果提出了碳纤维布约束混凝土的受压应力 应变全曲线方程 Based on the reasonable evaluation of the mechanical indexes of CFRP, the compression performance of CFRP-confined concrete was tested. The influence of the amount of carbon fiber cloth on the compressive strength and deformation performance of ordinary concrete is studied based on the experiment. The experimental results show that the specimen can improve the compressive strength of concrete after it is wrapped with carbon fiber cloth and can effectively improve the deformation performance of concrete. The effect of carbon fiber cloth increases with the increase of the amount of carbon fiber cloth. In the same amount of carbon fiber cloth, Article package effect is better than the effect of the entire package, that is, carbon fiber cloth in practical engineering applications have a problem of efficiency. The amount of carbon fiber cloth is converted into the equivalent amount of stirrups. At the same time, according to the theoretical analysis and test results, the full stress-strain curve of CFRP-constrained concrete
