Behavior of Reinforced Steel‐Fiber‐Concrete Beams in Flexure
Publication: Journal of Structural Engineering
Volume 113, Issue 12
Abstract
An analytical and experimental investigation is carried out into the deformational behavior and strength of reinforced steel‐fiberconcrete (RSFC) beams in flexure. Explicit expressions are derived for the moment‐curvature and load‐deflection behavior of simply supported beams based on idealized stress‐strain relationships for the steel‐fiber concrete (SFC) and the reinforcing steel. It is shown that RSFC beams with reinforcement have increased flexural strength and ductility at ultimate load when compared to similarly concrete beams with normal reinforcement only. RSFC beams also show less deformation than similar plain reinforced concrete ones at the same load level. Analytically predicted and curves are compared and found to agree well with the experimental data. The present approach is thus a useful tool in the analytical study and design of RSFC members.
