Validation of Coupled Simulation for Fire-Exposed Structures
Original language description
Structural fire assessment creates essential part in design and maintenance of steel, concrete or timber structures. Expensive empirical tests carried out in furnaces with gas burners present traditional approach. This article presents validation of linked computational approach for fire simulation and its effects on structure using adiabatic surface temperature approach. The simulation solves a weakly-linked problem, consisting of computational fluid dynamics (CFD), heat transfer and mechanical model. The temperature field from the CFD creates Cauchy and radiative boundary conditions for the thermal model. The temperature field from an element is passed further to the mechanical model, which induces thermal strains and modifies material parameters. This article presents a validation of the linked simulation, based on experiment with a timber beam exposed to fire in a furnace. The computation uses standard material properties given in EN 1995-1-2.
