Three dimensional transient analysis of temperature field for a steel beam installed beneath a ceiling and exposed to a localized fire source has been done. A general-purpose finite element code ANSYS was used for the calculations. Experimental heat fluxes to the beam surface were applied as boundary conditions. A correction method is proposed to derive net heat flux from incident heat flux data. In order to verify the simulations, correspondence has been examined on the temperature field between the data of former experiments and the results of analysis. The satisfactory agreement between the experimental and the calculated results confirms the effectiveness of the finite element method for determining the temperature field in the structural members exposed to a localized fire.
