Grandstands 5.1 to 10.5 51 to 105
Low rise (2 to 6 storeys) 9.0 to 12.8 36 to 51
Medium rise (7 to 12 storeys) 11.5 to 17.5 46 to 70
Car parks 8.9 to 16.3 31 to 57
Plant buildings
(w/o steel flooring) 7.8 to 10.9 70 to 98
(with steel flooring) 9.3 to 12.4 84 to 112
Heavy plant buildings
(e.g. BOS plants) 11.1 to 21.7 100 to 195
NOTES: Weights above include cold-formed and hot-rolled steelwork.
Weight comparisons per unit volume are more reliable indicators than weight per unit
area, hence the weights per unit area are simply derived from those per unit volume
using the typical heights.
Design studies can underestimate the weight of steel in the completed building by as
much as 30%.
sorry.i formed the above reply in table format .but it collapsed.
the first value (range) is "Typical range of weight perunit volume kg/m3"
the second value (range) is "Typical range of weight per unit area kg/m2"
