The Figure Q2 shows a simply supported slab of a car porch. The slab is supported by beams at each edge, and the slab and beams are not casted together. The size of the beams is 250 x 500 mm (excluding the slab thickness), while the slab thickness is 150 mm. Design Data: Finishes, ceiling and services form the characteristic permanent action (excluding self-weight of slab) - 1.5 kN/m2 Variable action=2.0 kN/m2 Concrete grade fax = 30 N/mm2 Characteristic strength of reinforcing steel fyk = 500 N/mm2 Unit weight of concrete - 25 kN/m Main bar size for beam 0-20 mm Main bar size for slab 6 - 10 mm Nominal cover Coom= 25 mm. S m B 6 m Figure Q2 (a) Calculate the total action (load) on the beam AB. (10 marks) (b) Calculate the reinforcement for bending in beam AB and sketch the arrangement of the reinforcement (10 marks)
