layer 28. In a doubly reinforced section, the required compressive reinforcement is provided for the: A) bending moment in excess of M lim of singly reinforced section B) bending moment equal to M lim of singly reinforced section C) shear force of the beam section D) shear force in excess of the V lim of single reinforced section

A concrete floor slab measuring 6 m x 3 m is simply supported on one side brick load bearing walls along the 6 m sides. The concrete slab is 200 mm thick and reinforced at the bottom as follows.1. Main reinforcement (short span i.e the bars are parallel to the short span), Y 12, shape code 34 @ 125 mm centre to centre,2. Distribution reinforcement (long span i.e the bars are parallel to the long span), Y 10, shape code 20 @ 300 mm centre to centre,3. Concrete cover, 30mm,4. Concrete strength, 40MPa.Draw the reinforcement layout for this slab, in plan and section, indicating all the reinforcement and necessary information required by the contractor. You must calculate and indicate the number of bars required on your drawing. You do not need to calculate the bar lengths and the curtailment. Your drawing must be neat.
