Reinforcement of Damaged Frame Joint with Carbon Fiber by Finite Element Analysis

Building carbon fiber reinforcement using soft ANSYS of damaged frame joints under cyclic loading of finite element model shows that the main effect of carbon fiber reinforcement of damaged specimen are to change failure types of joints from core area of shear failure into a mix of beam bending failure and core shear failure damage and to improve strength deterioration, stiffness degradation and seismic behavior of energy dissipation, though carrying capacity, rigidity and ductility of joint have little impact after reinforcement. The research provides some theoretical basis and certain practical value in carbon fiber reinforcement with great commercial future.
