Abstract:
Stress redistributes after the concrete structures strenthened with carbon fiber reinforced polymer sheet. It is a question of secondary loading.Many scholars have studied it and got a lot of achievements.This paper summarizes the methods and analyzes their advantage and shortcoming. Based on it, a new method is proposed.The method is developing in large-scale general software-Ansys by using adding new elements, constitutive relationship, failure criterion,and so on.The calculation formula agrees with the experimental data.
