纤维增强复合材料加固混凝土梁有限元分析

通过有限元方法对四根纤维增强复合材料加固的钢筋混凝土梁的力学性能进行了分析。与试验研究的结果比较后得出,通过建立正确的分析模型,有限元分析可以有效地模拟加固梁的力学性能。同时,对有限元分析得到比试验结果较低的极限承载力的因素进行了探讨。

Finite element analysis of reinforced concrete beams strengthened with FRP sheets

The mechanical behaviors of four reinforced concrete beams strengthened with fiber reinforced polymer (FRP) sheets were analyzed by using finite element method(FEM). The results were discussed in comparison with the experimental results, and it is found that with proper analytical models, finite element analysis can effectively simulate the mechanical behaviors of the strengthened beams. Several factors which may cause the lower ultimate loads in the finite element models were also proposed.
