CFRP-PCP板加固混凝土梁的抗弯承载力研究

Study on flexural capacity of CFRP-PCP plate reinforced concrete beams

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.

Through the test of 5 concrete beams with different reinforcement, different tension control stress and different CFRP-PCP plate,the flexural bearing capacity of reinforced concrete beams strengthened with CFRP-PCP plates in the process is analyzed. The test results show that the CFRP-PCP plates can improve the flexural bearing capacity of the members. And the calculation formula of the four failure modes is presented. Compared with the test results, the average error is less than 1%, which is in good agreement with the test results.
