DETERMINATION OF THE FIRE HAZARD REGION FOR STEEL STRUCTURES IN BEIJING NATIONAL STADIUM OF OLYMPICS
奥运国家主体育场钢结构防火保护区域的安全评估

Based on fire plume models, the smoke temperature above the fire source at different heights was predicted for typical fire scenarios of Beijing National Stadium of Olympics 2008. The strength and modulus of elasticity of steel under different temperatures were considered to determine the critical temperature value. Accordingly the fire hazard region for steel structures in Beijing National Stadium of Olympics 2008 was determined to be with in 10.2\,m above the seats.
