Abstract:

Computer fire models for simulating compartment fire environments typically require a mathematical formulation that couples the thermal response of the gases that fill the compartment and the thermal response of compartment barriers and partitions. The fire environment characteristics calculated by such models can be used to provide input, via thermal boundary conditions, to an uncoupled thermal-structural computer model for simulating and evaluating the combined thermal/structural performance of the barriers/partitions. The objective of such a combined analysis would be to determine, through analysis, the structural fire resistance of a barrier/partition design.
