摘要
本文给出了火灾温度场对国家大剧院壳体钢结构作用的安全评估。评估的目标是计算公共大厅内火灾时的温度场分布,验算钢结构温度小于250℃,不被火灾破坏。评估的方法是根据现场情况设计火灾场景,采用ComputationalFluidDynamics(CFD)软件进行模拟,通过其温度云图分布获得壳体钢结构的最危险点温度。
This article gives a safety assess of action of fire temperaturedistribution on shell steel structure of National Big Theater.The goal of the assess is computingthe distribution of temperatureduring fire in commonhall,verifying whetheror not the temperature of shell steel structure is lower than250Cel-sius degree and the structure will not be damagedby the fire.The methodof the assess is designing fire sce-narios dependingon the instance on the spot,simulating using ComputationalFluid Dynamics(CFD)software,ob-taining the temperatureof the most dangerouspositon using temperaturecontour.
