| 摘 要： | 利用有限元分析软件ANSYS对分别粘贴1层、2层、3层CFRP的钢筋混凝土梁建立简化模型,计算分析了三种加固梁在不同加载阶段的混凝土梁及CFRP的应力状况,研究结果表明:随着粘贴CFRP层数的增加,混凝土梁的受力状况可得到一定程度上的改善。

| Abstract: | Abstract： The paper adopts the finite element analysis software, ANSYS, to establish simplified models for the first, the second and the third CFRP reinforced concrete beam, calculates and analyzes the stress status of the three reinforced beams in the concrete beams at different load sta- ges and the CFRP, and proves by the research result that the stress status of the concrete beam can be improved somehow along with the addition of layer number of CFRP. |
