Abstract

Industrial floor slabs must be able to withstand heavy loads continuously throughout their service life. However, the use of conventional steel reinforcement still has limitations, such as the risk of cracking and corrosion that can reduce the structural lifespan. This study aims to analyze the performance of warehouse floor slabs using BarChip MQ58 steel fiber reinforced concrete (SFRC) as an alternative to partially or fully replacing conventional reinforcement. The research method involves numerical modeling using SAP2000 software, supported by manual calculation validation. The analyzed models include conventional reinforced concrete slabs with thicknesses of 17.5 cm, 20 cm, 22.5 cm, and 25 cm, and an SFRC slab using BarChip MQ58 fibers with a thickness of 20 cm. The main parameters evaluated are flexural capacity, maximum shear force, and vertical deflection. The simulation results show that increasing the thickness of conventional slabs effectively reduces deflection but does not significantly improve flexural capacity. In contrast, the BarChip MQ58 SFRC slab with a thickness of 20 cm achieves a flexural moment of 35.31 kNm/m, shear force of 261.26 kN/m, and deflection of 17.12 mm, which remains below the L/240 service limit. This performance is equivalent to conventional slabs with a thickness of about 22.5–25 cm. The study concludes that using BarChip MQ58 steel fiber reinforced concrete is effective in optimizing floor slab thickness without reducing strength and while meeting serviceability criteria.
