This paper presents a modeling approach to predict the flexural behavior of steel beams strengthened with carbon fiber reinforced polymer (CFRP) strips. The beams, W150×18, are simply supported and monotonically loaded until failure occurs. To examine the effect of CFRP-strengthening, selected beams are intentionally damaged by creating a notch at the tension flange. A three-dimensional finite element analysis is conducted, including bond-slip properties at the CFRP-steel interface. The CFRP-strengthening results in im-proved load-carrying capacity of the damaged beam and reduces strain localization near the damage.
