The following information is given:
Live load supported by slab = 1.5 kN/m²
Normal density concrete (Unit weight = 24kN/m³)
Clay brick masonry (Unit weight = 19 kN/m²)
Slab thickness = 170 mm
Wall thickness = 220 mm

a) Sketch the tributary loading areas for walls AB, CD, and EF.
b) Calculate the design load (in kN/m²) acting on the slab.
c) Calculate the design load (in kN/m) acting on walls AB and CD. Include the self-weight of walls.
Q2. Consider the plan layout of a three-storey office building shown in Figure 2. All walls comprise
standard clay bricks, are double skin masonry (collar jointed) and align from ground floor to roof.
All walls are load bearing to support the suspended slabs, and it is assumed that the roof and
floor slabs are of continuous in situ reinforced concrete construction.
