The fire development in timber buildings may have a different intensity depending on the location in which the fire originated.The large-space timber buildings are characterized by a large area with a comparatively low height, which makes fire-gas evacuation and air circulation difficult.This paper presents an investigation on the influence of the fire source location on the load-bearing capacity BARLEY MALT of timber beam exposed to fire.The finite element software Fire Dynamics Simulator (FDS) was used for numerical fire modelling, specifying the time-varying spatial maps of Melissa the fire-plume-gas temperature on the basis of the equations taken from the fluid dynamics methodology with aerodynamic and thermodynamic variables.The obtained results from the FDS were used to determine the load-bearing capacity of timber beam using the SAFIR software.

The results of numerical simulations showed that the fire source location has a significant influence on the load-bearing capacity of timber beam exposed to fire.
