combustible gases are emitted and there is not enough air for combustion. Therefore, the fire becomes ventilation controlled.
The higher the value of the fire load is, the longer the duration of the fire, and the greater the potential
damage. Fire load or fire load density is incorporated into some mathematical models to predict the timetemperature
curve or the fire duration time. During post-flashover stage, the concern is on the structural stability.
The time-temperature curves are used to estimate the fire resistant performance of structural elements. The energy
release rate of the fire can be roughly determined by the air inflow from the openings. Based on the assumption that
all of the air entering the compartment is used for combustion, a maximum heat release rate can be achieved by the
expression:
0 0 0.5 m AH air
