Abstract

A method suitable for design purposes has been developed which allows the approximate post-flashover compartment fire temperature to be plotted versus time in one curve, the general natural fire curve; time is then modified or scaled to take into consideration ventilation conditions and wall properties. In the analysis the common assumptions of constant and ventilation controlled combustion, uniform temperature, and wall losses proportional to the thermal inertia are made.The general natural fire curve is given an analytical expression, which is then used to calculate temperature in fire exposed insulated columns by a simple integration procedure. The results are plotted in handy diagrams, and temperatures obtained in columns exposed to natural fires and standard fires according to ISO 834 are compared.
