A hall of clear dimensions 15m×6m is to be covered by RCC slab flooring 12 cm thick resting over RS joists spaced at an interval of 3m, centre to centre. Floor finishing 2 cm thick is to be provided over the RCC slab. The live load on the slab is 4kN/m2. The joists are resting over 30 cm thick walls. Design an interior beam using code specifications. The unit weight of RCC and floor finish is 24 kN/m3. Apply all the necessary chicks.
