摘要
大型商场由于可燃物多、人员密度大,一旦发生火灾势必造成严重的经济损失和人员伤亡。因此,大型商场的抗火设计显得尤为重要。作为一种扁平类大空间建筑,大型商场的火灾机理不同于一般的大空间室内火灾。结合上海市第一百货商店老大楼混凝土框架结构对扁平类大空间商场建筑进行火灾模拟,分析商场空间及结构内部的温度场过程,并对火灾下整体结构的安全性进行分析,初步建立了扁平类大空间建筑在火灾作用下的全过程分析方法。
Many large markets are built across the country in recent years along with the raise of the people＇ s material and cultural living standards. Due to its large quantity combustible materials and numerous staff, in the case of fire, it is bound to engender great loss of property and personnel. So the fire-resistance design of large markets is very important. Large markets are fiat large space. The fire in flat large space is different from other large space fire. In this paper, the fire in flat large space with an example of the No. 1 Department Store of Shanghai was simulated. The temperature distribution within the whole space and the structure was analyzed, and the whole structure safety was analyzed too. The full-process analysis method on fire for flat large space structures was established.
