    Abstract

    Strengthening of concrete structures in flexure with externally epoxy-bonded carbon-fiber-reinforced plastic (CFRP) laminates is becoming an increasingly popular retrofit technique along researchers and engineers worldwide. A reliability study of such structures IS .the topic of this paper. First, considering the statistical character of the design variables (geometry, material properties), the effect of. changes In these variables on the flexural capacity of CFRP-strengthened members is established. variabilities In concrete strength and CFRP failure strain and a:ea fraction .are most influencial on flexural strength. Next, strength reduction factors are derived, with the 31m of achieving a uniform reliability 10dex of about three over a broad spectrum of design conditions. A general strength reduction factor Φ = 0.80 is .proposed. Finally, the effect of each design variable on the reliability of the system IS examined and quantified 10 terms of the reliability index.
