Abstract

Abstract: In this paperby means of theoretical derivation and experimental verificationthe effect of the thickness of carbon fiber laminate （CFL） on the failure mode of the strengthened RC （Reinforced Concrete） beam was investigated．In the investigationa method and corresponding equations were proposed to estimate the fa-i lure modes of4 groups of beams．The theoretically estimated results show that the failure mode of the RC beam strengthened with CFL changes with the thickness of CFL and that 4kinds of failure modesnamelythe tension fracture of CFLthe debonding fracture of interface or the cover concrete separationthe concrete crush and the mixed failure modeare respectively related to the4thickness regions．All these estimated results were finally verified by some tests．

Key words: carbon fiber laminate, thickness, failure mode, RC beam
