| 摘 要： | 用有限元理论分析碳纤维增强材料(CFRP)约束混凝土梁的加固效应,并与试验结果比较,结果表明通过合理选择有限元分析数值模型,可较好地模拟CFRP布约束混凝土梁的受力性能,在此基础上进一步对CFRP约束的混凝土梁的受力进行非线性仿真分析,论证CFRP加固混凝土梁的优化设计问题。

| Abstract: | The effect of CFRP sheets in strengthening of RC beams is studied by using the theory of finite element analysis and is compared with the experimental results.The comparative results indicate that the bearing capability of CFRP sheets in strengthening of RC beams can be simulated better by selecting the right finite element model.Then,the non-linear simulated analysis of CFRP sheets in strengthening of RC beams is done further.And the optimum deign problem of CFRP sheets in strengthening of RC beams is demonstrated. |
