| Abstract: | Based on the test of five high-strength reinforced concrete beams strengthened with externally bonded carbon fiber reinforced sheets which includes three precracked beams and two reference beams, the influence of damaged degree were studied and analyzed, It is shown that deferent damaged degree shows similar limit loads, but deferent section stiffness. |
