An internal 2nd level floor system of an office building is composed of a slab cast monolithically with stiff beams 400 mm wide whose centrelines are on the grid shown in Figure below. The reinforced concrete density is 2400 kg/m 3 . Note the following specified conditions of service. Concrete Strength, f’c (MPa) = 20 L (m)= 5.5 L1 (m) =6.8 L2 (m)= 6.0 Answer the following questions using the simplified methods in AS3600. 1. Determine the appropriate reinforcement cover. 2. Determine the appropriate slab thickness to satisfy serviceability requirements as specified in AS3600 and design the reinforcement for panels A and B (Use N12 bars throughout). Sketch the reinforcement details for the above panels.
