Abstract
The slab is one of the most important members in building structures because it covers the largest area of the building. The structural type and construction method of a slab can have a large influence on the construction period and the amount of structural materials. This study investigates a simplified one-way slab system with simple construction procedures. The simplified slab system consists of a composite steel deck plate and steel fiber reinforced concrete (SFRC) without conventional steel reinforcing bars. The composite steel deck plate can replace the tensile reinforcing bars and concrete form, and the SFRC makes temperature reinforcement unnecessary. Four specimens were tested to analyze the flexural performance and serviceability. The test results were analyzed from the viewpoints of flexural performance regarding flexural load capacity, stiffness, deflection, crack development, and failure mode. The test results indicate that the overall flexural performance of the system was suitable in slab members, even though reinforcing bars were not used. It has higher flexural stiffness and shows lower crack height than a conventional RC slab.
