基于CFRP布加固钢筋混凝土梁的抗弯性能试验结果,假定梁在线弹性范围内基本符合平截面,探索了不同方式CFRP布加固后的钢筋混凝土梁的抗弯承载能力。结果表明,研究所得的CFRP布加固梁底面、侧面时,梁的抗弯承载能力计算公式所得结果较试验值偏大,可作为初步设计的估算公式使用。
Based on the test results of flexural strength of RC beams strengthened with CFRP sheets, the flexural load carrying capacity of RC beams strengthened with different CFRP sheets is explored assuming that the beam is basically in the linear elastic range. The results show that when the CFRP sheet is used to reinforce the bottom and the sides of the beam, the bending capacity of the beam is larger than the experimental value, which can be used as the initial design estimation formula.
