碳纤维布增强损伤钢筋混凝土梁的有限元分析

Finite element analysis of damaged RC beam strengthened by CFRP sheets

针对试验梁,利用有限元软件,合理的划分单元、建立非线性有限元模型,并进行分析。通过与试验的对比研究发现,CFRP能够很好的提高损伤结构的承载力,有限元分析结果与试验结果较好吻合。因此有限元分析可以用于CFRP布加固损伤钢筋混凝土梁的研究。

In the use of finite element software,this paper divides unit reasonably and builds nonlinear finite element model in order to analyze test beam.By comparative study with the experiment,it is shown that CFRP can improve the bearing capacity of the damaged structure very well,and the finite element analysis result matches the test result well.Therefore,the finite element analysis could be used for the study of CFRP reinforced damage concrete beam.
