Calculation: Given, Total span = 6 m Depth of beam = 85 mm per 1 m span Total Depth of beam = 0.085 × 6 = 0.51 m Width of beam = 230 mm = 0.230 m We know, Unit weight of RCC structure = 25 KN/ m3 Volume of the section = L × B × H Volume of the section = 6 × 0.230 × 0.51 Volume of the section = 0.7038 m3 Dead load of the beam = Unit weight × Volume of the section = 25 × 0.7038 = 17.595 KN Factored dead load of the beam = 1.5 × 17.595 = 26.39 KN
