The second storey of an office building consists of composite steel deck 75mm deep with 90mm concrete cover (normal density cover). The floor is topped with carpet. The composite steel deck also supports ducts/pipes and wiring and fireproofing. Allow 1.0kPa dead load for partitions and a live load of 2.4kPa due to occupancy.

a) Determine the total dead load supported by the composite steel deck

b) Determine the total factored combined load of ultimate limit states

c) Determine the load for serviceability criteria of the following: Deflections are limited to L/360 under live loads or L/240 under total load, whichever governs.
