Transitioning from solid slabs to a flat slab system in reinforced concrete structures offers several advantages in terms of construction efficiency, structural performance, and cost-effectiveness. When implementing this transition, there are key concepts and considerations to bear in mind for a successful and seamless integration. One of the primary benefits of adopting a flat slab system is the reduction in overall floor depth, leading to greater headroom and architectural flexibility within the structure. This design also simplifies construction and reducing material costs. However, careful consideration must be given to reinforcing detailing to ensure adequate load-bearing capacity and structural integrity. This research primarily focuses on examining how beam depth affects the bending moment and deflection of reinforced concrete slabs and beams under gravity loads. Structural modeling will be performed using SAP2000 software. The analysis will yield results pertaining to structural performance, including deflection and maximum bending moment. The findings reveal that the internal forces, especially the bending moments in the beams, increase with an increase in beam height. Additionally, the deflection of the two-way slabs and beams decreases as the height of the supporting beams increases.
