Factors to consider for Fire Engineer & Structural Engineer(a) The selected fire cases should be critically reviewed to ascertain if they generally
cover the worst scenario.
(b) The derivation of the fire load should be conversant with the local condition rather
than simply refer to overseas fire load data.
Some unprotected steel members might be subjected to a temperature close to the limiting temperature in case of fire. However, the structural design of the steel structure should take into account the stress reduction factor of steel at elevated temperature.
The derived surface temperature of the material subjected to elevated temperature has to account for the heat effects of thermal conductivity of materials, which may further raise the surface temperature.
The behaviour of natural fire set up of an open frame structure in the laboratory may be different from the real fire on the spot. In particular, the prevailing wind and other actual building layout, which may accelerate and increase the temperature of the structural material, have to be taken into consideration.
Calculation of fire resistance ratings, based on full compartment burn-out.
Development of suitable acceptance criteria for the design and use of timber, steel, concrete and glazing and their material limitation.
