Flexural Behavior of Double-Layer Concrete Beams Composed of Normal and Steel Fiber-Reinforced Concrete

This investigation studies the flexural performance of double-layer reinforced concrete beams composed of ordinary concrete and steel fiber reinforced concrete (SFRC). The study evaluates the effects of bottom layer thickness, shear span ratio (a/d) and straight steel fiber volume fraction on structural behavior. The study project comprises twenty reinforced concrete beams, all specimens had…
