摘要
通过试验研究了碳纤维布、玻璃纤维布和玄武岩纤维布加固钢筋混凝土方形板的情况。并且运用有限元软件ANSYS对试验情况进行模拟,分析了试验中出现的纤维布的不同破坏结果。分析的结果表明,纤维布的纵横双向受力以及较大的应力集中是导致其提早破坏的主要原因。根据试验以及有限元分析的结果,对采用纤维布加固方形板的形式进行了改进,并取得了较好的效果。
Based on experimental research on R.C. square slabs strengthened by CFRP, GFRP and BFRP sheets, a nonlinear finite element method is used to analyze the different failure modes on reinforced concrete sheets in the experiment using ANSYS program. The analyzing results indicate that the longitudinal and the transverse stress in the fibres and the stress concentration are the major reasons that lead to the failure of the fibres ahead of time. According to the results of the experiment and the nonlinear finite element analysis, we improve the form of the slabs strengthened by sheets and get a good effect.
