Abstract

The shear behavior of steel fiber reinforced concrete (SFRC) beams has been assessed in a large number of previous studies. However, the shear strength of corroded SFRC beams without shear reinforcement is still an unresolved topic. In this paper, the finite element models of non-corroded and corroded SFRC beams have been constructed and verified regarding load-displacement curves, crack patterns, and failure modes. Finally, a parametric study also was performed to assess the effect of essential design parameters on the shear strength of SFRC beams under corrosion attacks. The results show that the reinforcement corrosion degree and concrete compressive strength are the most influencing parameters on the shear strength of SFRC beams, followed by the shear span-to-depth ratio and the steel-reinforced ratio.
