Abstract
Nowadays, there have many reinforced concrete frame structures in China, which need to be reinforced in the event of strong earthquake. Therefore, quasi-static analysis method has adopted to investigate the seismic performance of the five story concrete frame structures and the different reinforcement schemes on the seismic performance of reinforced concrete (RC) structures. The results are shown that the numerical simulation of RC structures was verified by the Open Sees finite element method based on the existing experimental data. It was found that the weak layer of the RC frame structure mainly occurs in the plastic hinge region of the middle and lower floors of the RC frame structure. It was suggested that only the plastic hinge region of the middle and lower half of the RC frame structure and the bottom of the plastic hinge region of the bottom column of the RC frame structure could be reinforced, which will provides a theoretical basis for the RC frame reinforced method in the future.
