Abstract
The effect of reinforcement configuration (steel fibers and a rebar) on the mechanical performance of a multiribbed composite slab (MCS) has been investigated. Four full-scale multiribbed composite prefabricated slabs with different volume fractions of steel fibers and the same total steel content were manufactured using a steel-fiber-reinforced concrete, foam concrete, and normal concrete. Various technical indicators were detected under the same static load, including the crack resistance, yield load, ultimate load, maximum deflection, destruction pattern, and stress of the steel rebar. The MCS exhibited excellent properties, and it is concluded that such slabs can be recommended for use in practice.
