碳纤维加固混凝土梁位移ANSYS模拟研究

摘要

For beam mid-span displacement, theoretical calculation and ANSYS modeling computational analysis have been done to quantitative analysis of the effect of carbon fiber reinforcement beam, and improve the further relevant reinforcement theory, to provide a theoretical and com- putational support for real-strengthening works. The analysis shows that the values and trends of finite element analysis and theoretical calculations are very similar, which indicates that the finite element analysis is capable to simulate the beam actual stress state, the displacement of FRP rein- forced beam decreases 14.08%.%针对梁体跨中位移，通过理论计算以及ANSYS建模分析计算分析比较，定量分析碳纤维加固梁体的效果，进一步完善相关加固理论，为现实加固工程提供理论和计算支持，分析表明，有限元分析计算值和理论计算值在数值和发展趋势上都有很大的相似性，说明有限元分析能较好的模拟梁体实际受力状态，FRP加固后梁体位移减小14．08％。
