In this paper, collapse temperature of steel plane frames considering fire spreads are discussed by using numerical analyses based on nonlinear finite element methods with beam elements. The steel frames subjected to the horizontal fire spread in the same floor and the vertical fire spread to the upper story are used for the numerical analyses, respectively. From the numerical results, it was clarified that the fire spread in the frame did not have the significant influence on both collapse temperatures and load redistribution capacities for the steel frame.
