| 摘 要： | 应用理论计算公式,对影响抗弯承载力的CFRP片材厚度、弹性模量以及混凝土强度等参数进行了分析,结果表明,使用弹性模量高、厚度大的CFRP片材加固的组合梁,承载力提高更大;采用高混凝土强度的梁,其极限抗弯承载力提高效果更明显。

| Abstract: | Equations were used to present an analytical parametric study on the flexural capacity of the steel-concrete composite beam that has been strengthened with CFRP sheets. The important parameters included were the thickness of the CFRP sheets,the modulus of elasticity of the CFRP sheets,the concrete compressive strength. The results show that strengthening using CFRP is more efficient for composite beams with higher modulus,thicker CFRP sheets and higher concrete compressive strength. |
