This paper proposes a relationship between the minimum thickness of glass fiber reinforced polymer-reinforced concrete (GFRP-RC) solid non-prestressed one-way slabs and clear span. In total, 68 slabs were analyzed and designed using ACI 440.11-22 Building Code addressing strength, serviceability, and detailing criteria. Slabs were analyzed with four end conditions: simply supported, one end continuous, both ends continuous, and cantilever. Based on the analysis and design, a relationship similar to the one given in ACI 318-19 Table was proposed to provide designers with a way to avoid tedious calculations for the deflection of GFRP-RC slabs. It was observed that irrespective of using maximum or minimum reinforcement limits, minimum slab thickness values were always lower for GFRP-RC slabs than conventional steel-RC slabs. Hence, using Table in ACI 318-19 for the calculation of a minimum slab thickness of GFRP-RC slabs will be conservative when the concrete strength is 4000 psi or more and the deflection limit is l/240.
