摘 要: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。
Abstract: Based on the test results of the flexural performance of reinforced concrete beams strengthened with CFRP sheets, it is assumed that the beam is in line with the plane section within linear elastic range. Bearing capacity of reinforced concrete beam strengthened with CFRP cloth in different ways was explored. The results show that the proposed formula could estimate flexural capacity of the reinforced concrete beams bottom or side strengthened with CFRP sheets in preliminary design, for its results are larger than tests results. The research method can provide a reference for the calculating of flexural capacity of reinforced concrete beams strengthened with CFRP cloth.
