The purpose of this paper is to establish a predictive method for the temperature field of a metal column exposed to a localized fire using the Finite Elements Method. In this report, we carried out the experiments on a steel column surrounded by fire sources to examine boundary conditions and analysis model used in FEM calculation. ln the experiments, Heat flux and temperature distributions along the column were measured. Then we calculated the temperature distributions of the column by FEM using the measured heat flux data. From the calculation, we speculated the convective coefficient on the heated steel surface, thermal balance parameters, and so on. The temperature distributions along the steel column adjacent to the localized fire are calculated with speculated coefficient, and the method to calculate the temperature of member subjects exposed to a localize fire is established.
