Research on CFRP External Pre Stress Reinforcing Vertical Crack of Box Girder Roof
Xin Zhong Wang · Hunan City University
摘要整理
the article is about longitudinal crack of concrete box girder roof, and it designed a reinforcement model. As the pre stressed material, CFRP could reach 30% of reinforcement efficiency under different loads in design model through external reinforcement upon calculation and analysis. And its crack width greatly reduces. In this way, the reinforcement purpose could be realized, and the mechanical properties of CFRP concrete could be fully played. The effect is obvious.
