【 摘 要 】

This paper aims to study the effect of reinforcement configuration (steel fibre and rebar) on the mechanical performance of composite slabs of the same total steel contents. We manufactured four pieces of fullscale multi-ribbed composite prefabricated slabs with different reinforcement configurations by using steel fibrereinforced concrete, foam concrete, and normal concrete. The multi-ribbed composite prefabricated slab has many excellent properties, such as light weight, good thermal and sound insulation. Thus, it can be applied to fabricated structures. In addition, the composite prefabricated slabs with the same total steel contents but with different reinforcement configurations were studied under the same static load, and many technical indicators such as crack resistance capacity, yield load, ultimate load capacity, maximum deflection, destructive pattern, and stress of steel rebar were obtained. Results indicate reinforcement configuration has a significant effect on the mechanical performance of composite prefabricated slabs with the same total steel contents, and composite prefabricated slabs reinforced with longitudinal rebar and steel fibre (volume fraction is 1.5%) have the best mechanical performance and ductility.
