摘　　要：为确保天津奥林匹克中心体育场钢结构屋顶的安全,对其耐火性能进行分析。通过火灾危险性分析,设定火灾场景,利用火灾动力学模拟软件FDS和经验公式分别计算设定火灾场景下钢构件的最高温度,并计算分析钢构件的高温特性。计算结果表明,在设定火灾场景下,体育场的屋顶钢构件可不进行防火保护。Analysis on fire resistance behavior of steel roof of Olympic stadium in Tianjin is carried out for the purpose of roof safety. Based on fire risk analysis, design fire scenarios are set. The maximum temperatures of steel structure in the design fire scenarios are calculated by Fire Dynamics Simulator empirical equation. According to the results, the high temperature characteristic of the steel member is analysised. The results showed that the steel roof of stadium may not carry out fire protection.
