one way slab design

A one-way slab is a reinforced concrete slab that primarily bends in one direction due to its support conditions. It is commonly used in building construction where the length-to-width ratio (L/B) is greater than or equal to 2. In this type of slab, the main reinforcement is placed along the shorter span to resist bending moments, while the longer span provides minimal structural resistance. One-way slabs are supported by beams or walls on opposite sides, transferring loads primarily in a single direction. Designing a one-way slab involves determining its thickness, reinforcement, load distribution, and deflection limits according to codes such as ACI 318 or IS 456. Factors like live loads, dead loads, and serviceability requirements influence the slab’s design. One-way slabs are widely used in residential, commercial, and industrial buildings, offering a simple and cost-effective flooring system for spans up to 6 meters (20 feet).
