“…The sensitivity to this assumption is studied here. Peak temperatures in small fires have been measured in the range of 800 to 1000°C [23], while those in larger compartments have been found to be up to approximately 1200°C [24]. The FDS simulations of a localised 147MW fire in a large compartment shown in Figure 2.3 agree with this range and predict peak near field temperatures ranging from 800 to 1050°C, depending on the ventilation scenario.…”

“…Hence it is assumed that there is direct contact and peak flame temperatures are used in this methodology. These temperatures have been measure in small fires in the range of 800 to 1000°C [23] and up to 1200°C in larger fires [24]. The maximum value of 1200°C is chosen here for the near field temperature to represent worst case conditions.…”

Upward flame spread over discrete fuels has been analyzed through experimental research on vertical arrays of alternating lengths of PMMA and insulation. By manipulating the lengths of the PMMA fuel and the insulation, several important trends related to flame spread were identified and assessed.The peak flame spread rate for arrays with 4 cm lengths of PMMA occurred at a fuel percentage of 67%; for arrays with 8 cm PMMA, a peak flame spread rate occurred at fuel percentages of 67%, 80%, and 89%. It has been hypothesized that increased air entrainment at these fuel percentages maximizes the flame spread rate.Based on observed trends, this study proposed a method for approximation of the fuel spread rate at various fuel percentages. Given reasonable estimates for the homogeneous flame spread rate and the lowest fuel percentage that sustains spread, an estimation for intermediate spread rate values is feasible.

“…The maximum possible heating in a structural element would result from direct contact with the flames. These temperatures have been measured in small fires in the range of 800 to 1000°C (Audouin et al, 1995) in larger fires up to 1200°C (Drysdale, 2011). The far-field temperature decreases with distance from the fire.…”

2In this study, structural response of a seismically designed steel moment-resisting frame subjected to travelling fire is investigated. This is to determine the structural strength of a generic frame designed for an extreme load when subjected to fire as another extreme load in addition to quantifying the effect of travelling fire size on its collapse behaviour. In this study, using the concept of travelling fire, and calculating the thermal field applied to structural elements, a generic frame was examined against a family of fires travelling across its first floor. In this regard, the resolved far-field gas temperatures dependent on the distance to the centre of fire were considered in order to calculate the temperature at the unprotected steel members. Analysis results revealed that fire size can deeply affect the total collapse time of a frame so that by reducing the fire size to a half or a quarter, collapse time increases by 19% and 62%, respectively. It was also suggested that columns of such structures should be designed against travelling fire considering the effect of load redistribution by which axial forces of columns might be doubled compared to the nominal loads applied to them prior to fire.
