CONCEPT:Torsional Reinforcement: It is provided as per guidelines provided in annex D of IS 456: 2000.In a two WAY spanning slab torsional reinforcement shall be provided at corners of the slab. The torsional moment are high near the corner therefore, torsional reinforcement is essential to prevent the corner slab from lifting and prevents cracks. It is provided at corners in the form of a mesh, sometimes referred as corner reinforcement.It shall CONSIST of top and bottom reinforcement, each with LAYERS of bars placed parallel to the sides of the slab and extending from the edges a minimum distance of one-fifth of the span (0.2 times of the span).The area of reinforcement in each of these four layers shall be three-quarters of the area required for the MAXIMUM mid-span moment in the slab.The following diagram illustrates the mesh of corner reinforcement: "> CONCEPT:Torsional Reinforcement: It is provided as per guidelines provided in annex D of IS 456: 2000.In a two WAY spanning slab torsional reinforcement shall be provided at corners of the slab.
