摘要
碳纤维复合材料(cFRP)加固混凝土结构是一种新型结构加固方法。在大比例模型试验的基础上,应用有限元程序对T型梁进行了加固分析,以研究CFRP布加固对混凝土梁抗弯能力及刚度的提高程度。分析结果表明,CFRP布加固可应用于大型钢筋混凝土桥梁。
CFRP strengthening is a new technique for the strengthening of concrete structures. On the basis of large model test and finite element analysis, the influence on bending strength and stiffness of concrete beams strengthened with CFRP sheets is presented. The results indicate that CFRP sheet can be applied to the strengthening of concrete bridges.
