of contents and the structure itself. The article "Fire
Loads in Office Buildings" (J. of Structural Engr.,
1997: 365â368) gave the following cumulative percentages
(read from a graph) for fire loads in a sample of
388 rooms:
Value 0 150 300 450 600
Cumulative % 0 19.3 37.6 62.7 77.5
Value 750 900 1050 1200 1350
Cumulative % 87.2 93.8 95.7 98.6 99.1
Value 1500 1650 1800 1950
Cumulative % 99.5 99.6 99.8 100.0
