Abstract

Abstract

Experimental research on the flexural behavior of 17 RC beams strengthened by carbon fiber sheet( CFS) under quadratic loading has been carried out. The experimental researches considered that how the reinforcement ratio of the longitudinal reinforcing bar, the quantity of carbon fiber sheet as well as stress level of the beam influence the CFS strengthening effect. Test research showed that the carbon fiber sheet has good strengthening performance, the stress at first stage can reduce the strengthening effect, and the reinforcement ratio and the CFS quantity have greater influence on the strain of CFS.
