【摘要】 许多大体量建筑由于结构特点和使用功能的特殊要求在划分防火分区时存在困难。通过设置内部防火间距将可燃区块进行划分,以减少可燃物间的辐射热交换,可以达到控制火灾蔓延的目的。提出了基于热辐射计算的内部防火间距的设计方法,并采用案例加以说明。更多还原

【Abstract】 It is very difficult to divide fire separations in large space buildings because of their structure features and their special functions.The object of controlling fire spread can be achieved by setting up an appropriate separation distance to isolate combustibles and reduce radiation heat exchange.A design approach for interior fire separation distance was presented based on heat radiation calculation.The approach was also validated by an actual case.更多还原
