چکیده
In this paper, a new combined form of Glass Fiber Reinforced Plastic (GFRP) column and steel fiber mortar reinforced damaged Concrete (RC) is proposed. With the help ABAQUS finite element software, model GFRP tube RC established. Based on experiment strengthening column, parameters such as winding angle tube, strength section loading mode are studied by numerical simulation. The results show that axial compression bearing capacity composite structure increases with increase between 45° direction. change strength, initial damage different methods, have little change. On basis simulation research, calculation equation columns strengthened modified superposition method, comparison shows agreement good.
