One Way Slab
One-way Slab : One-way slab is a type of concrete slab in which loads are transferred in one direction to the supporting beams and columns. Therefore, the bending occurs in only one direction. The design of one-way slab is simple and can be carried out easily. Differentiate One-way Slab from Two-way Slab : When a rectangular slab is supported on all four sides, but the ratio of the longer side, L, to the shorter side, S, is 2 or more, L/S ≥ 2.0, then, the slab will act as a one-way slab, with bending primarily occurring in the short direction. The main reinforcement is placed in the shorter direction which is the span, while shrinkage reinforcement is provided in the longer direction to limit cracking. When the slab is supported on only two sides, the load will be transferred to these sides regardless of its ratio of longer span to shorter span, and it will be classified as a one-way slab. One way slab behavior : The structural action of a one-way slab can be visualized in terms ...
