A simply supported roof slab is designed as a strip of unit width. The dimensions of the slab are 1.5mx4.5m and it has a maximum bending moment of 25kNm, then the total depth of the slab incorporating the 20 mm clear cover and 10 mm allowance for reinforcement is (take M25 concrete and Fe 410 steel)

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.
