A reinforced concrete slab has to be designed for an entrance porch to a hotel (C3 category). The slab should be supported over two load bearing concrete walls as shown in Figure 2 and Figure 5. Thickness of the slab is 230 mm. To design the slab, the following design data are given.
Concrete class: B30
Exposure class: XC3
Design life: 50 year
Steel type: B500NC
Density of concrete: 25 kN//m3
a) Calculate the design bending moments (Mu) at support A and at span All at the Ultimate Limit State.
b) Design bending reinforcement (i.e. calculate the required steel area, spacing between ban and check for minimum reinforcement) at “support A” and at “span AR” using bar size: 12 mm bar diameter for principal reinforcement and 10 mm bar diameter for transverse reinforcement.
