Q2: A simply supported reinforced concrete slab is subjected to an imposed load of 2.8 kN/m2. The self-weight of the finishes above the slab = 2 kN/m2 as shown in the figure below. Design the slab for moderate exposure conditions and 3 hours of fire resistance. Assume that the characteristic material strengths are fcu= 40 N/mm2 and fy= 460 N/mm2 and the concrete density = 24 kN/m3. Design the slab.
