Experimental Study on the Fatigue Properties of RC Beam Strengthened by Prestressed CFL

Abstract

Bonding prestressed CFL to strengthen reinforced RC structures can improve the bending capability of structures and the working efficient of CFL. Base on the fatigue experiments of 4 RC beams strengthened by prestressed CFL, the present paper analyzes the fatigue properties of prestressed CFL reinforced RC beams. Comparing with the experimental results of strengthened RC beams without prestress, it can be concluded that the prestressed technology can improve the reinforcing effect and fatigue lives.

Study on Pre-CFRP Reinforcement Based on Anti-Arch Method

“…In view of the above problems, people began to study the Pre-CFRP reinforcement method based on the deformation of the beam itself. FEM was used by Ouyang Lifang to study the reinforcement effect by anti-arch deformation of the beam [3]. Zhao Qilin used anti-arch technique to reinforce steel structure [4].…”
