通过对5根混凝土梁不同的加固情况、不同的张拉控制应力以及不同的CFRP-PCP板中混凝土的材质进行试验,分析CFRP-PCP板加固混凝土梁受力过程中的抗弯承载力.试验结果显示,CFRP-PCP板加固梁能大幅度提高构件的抗弯承载力.并提出了试件4个破坏模式的计算公式,与试验结果进行对比,平均误差在1%以内,两者吻合情况良好.
The flexural capacity of CFRP-PCP reinforced concrete beams subjected to different loadings was analyzed through different reinforcements of five concrete beams, different tension control stresses and different materials of concrete in CFRP-PCP panels. The test results show that The CFRP-PCP reinforced beams can greatly improve the flexural capacity of the members, and the calculation formulas of the four failure modes of the specimens are proposed. Compared with the experimental results, the average error is within 1% and the agreement between the two is in good agreement.
