Paper Title:
Experimental Study on the Damaged RC Frame Structure Strengthened by Composite Reinforcement of CFRP and Steel Plate under Low-Cycle Repeated Load
  Abstract

We take low frequency cyclic reverse tests to three RC frames made with the same dimension. One of frames is not reinforced for reference; the others are loaded to steel yield and then completely uninstalled. One of injury RC frames is strengthened by CFRP, and we use CFRP and steel plate mixed to strengthen the other one. Then experiment under low-cycle repeated load for strengthened frames have done again, and two seismic reinforcement methods are compared by the test performance of the framework. The results show that compared to CFRP, mixed reinforcement can improve the structural bearing capacity more effectively. The frame strengthened by CFRP reflects better energy dissipation and ductility than another.
