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
ABand
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
=See table in appendix Density of concrete
=24k(N)/(m^(3))Diameter of Rebars for slab
=16mmDiameter of Rebars for Beams and Columns
=25mmDiameter of Links for Beams
=8mmStrength 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
=0.40Support condition for beam and slab = simply supported Questions: Determine whether an overall depth of
150mmis 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.
