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))`

`=`

See table in appendix Density of concrete

`=24k(N)/(m^(3))`

Diameter of Rebars for slab

`=16mm`

Diameter of Rebars for Beams and Columns

`=25mm`

`=8mm`

Strength of concrete

`=35(N)/(m)m^(2)`

Strength of reinforcement steel

`=450(N)/(m)m^(2)`

Service stress of steel reinforcement

`=`

Exposure condition of structure

`=`

Moderate

`(b)/(d)`

ratio for beams

`=0.40`

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.
