In the design of two-way slab restrained at all edges, torsional reinforcement required is
Open in App
Solution
The correct option is A 0.75 times the area of steel provided at midspan in the same direction
For restrained slab, the area of reinforcement in each of the four corner layers shall be three quarters of the area required for the maximum mid span moment in the slab simply supported on both edges meeting at that corner. lf the corner contained by edges over only one of which the slab is continuous, torsion reinforcement equal to 0.375 times the area of reinforcement provided the mid-span in the same direction shall be provided. If both edges are continuous, no torsion reinforcement shall be provided.
