Given below is the plan view of a reinforced concrete floor slab for a 'general use office space'. The slab is supported on two beams
AB
and
CD
, which are further supported by rectangular columns at each end as shown in the Figure. The floor slab is subjected to a combination of dead loads from partition walls and fittings, its self-weight, as well as live loads. The spans between supports are as shown. Dead load from partition walls and fittings:
3.0k(N)/(m^(2))
Live load on slab

Support condition for beam and slab = simply supported Questions: Determine whether an overall depth of
150mm
is suitable for the slab system above, otherwise determine the suitable overall depth rounded to the nearest
10mm
. Design the flexural reinforcement for the slab Determine a suitable dimension for the beams considering all the loads from slab as well as the self-weight of beam. Check whether the beam meets slenderness requirements. Design the flexural reinforcement for the beam.
