Aug 30, 2021 · The one way slab can be defined as the type of slab in which the ratio of the longer span to the shorter span is greater than two. Mathematically; (Longer Span / Shorter Span) ≥ 2. In other words, the one-way slab is supported by beams in such a way that the load is carried along one direction.
The slabs having ratio of longer length to its shorter length (L y /L x) greater than 2 is called one way slab otherwise as two way slab. In one way slab main reinforcement is parallel to shorter direction and the reinforcement parallel to longer direction is called distribution steel.
For one way slab, main reinforcement is computed by a formula (In limit state design) that is determined by comparing compressive force as well as tensile forces. Ast = 0.5 Fck/Fu [1-√1-2.6Mu/Fck.b.d]b.d. and the distribution steel is computed as. 0.15% of Ag, for mild steel.
The ACI 318-19 provides a number of requirements regarding slab thickness, concrete cover, and reinforcement ratio which facilitate the design process. For instance, the ACI 318-19 specifies minimum slab thickness that satisfies deflection.
Dec 30, 2021 · Basically one way slab is the one in which the section of slab is supported on two opposite direction beams. In this case the main reinforcement bars are provided along the spanning direction in order to resist the load. The ratio of L/B is important factor can be considered in one way slab design.
The primary reinforcement for a one-way slab is calculated using a formula (in limit state design) that is found by comparing compressive and tensile forces. Ast = 0.5 Fck/Fu[1-√1-2.6Mu/Fck.b.d]b.d The distribution steel is calculated as follows: For mild steel, 0.15 percent Ag is used.
Dec 31, 2023 · Reinforcement in a one-way slab is designed to resist bending due to loads applied perpendicular to the supporting edges of the slab. One-way slabs are typically supported on two opposite sides and are designed as beams spanning between these supports.
Nov 30, 2020 · One-way Spanning Solid Slabs. Clause 5.3.1 (5) of EN 1992-1-1:2004 suggests that a slab subjected dominantly to uniformly distributed loads may be considered as one-way spanning if either: It possesses two free (unsupported) and sensibly parallel edges.
