Abstract

The purpose of this paper is to study how the high-temperature smoke would affect the steel constructions of the national theater. CFD method and empirical equations are employed to calculate the temperatures in the huge public hall interactively. A steel construction safe temperature of 250℃ is determined, and the calculated smoke temperatures are under the determined steel construction safe temperature, which proves the steel constructions of the national theater will pot be damaged by the smoke produced in fires.
