在过去10年中,烟控系统设计和评估方法发生了巨大变化。早在1991年,国际建筑设计规范(IBC)前身的统一建筑规范(UBC)中就已对烟控系统设计提出了基本要求。对于高层建筑和大排烟量中庭建筑的分区烟控系统,1991年UBC要求火灾区域的通风换气次数应达到6次/h,此时要求采用主动机械
In the past decade, tremendous changes have taken place in the design and evaluation of tobacco control systems. As early as 1991, the basic requirements of smoke control system design were put forward in the Unified Building Code (UBC), the predecessor of the International Building Code of Design (IBC). For high-rise buildings and large smoke volume atrium building zoning control system, UBC in 1991 required the ventilation area of the fire frequency should reach 6 times / h, this time requires the use of active machinery
