楼梯间增压的传统技术本质上是规定性的，主要基于保持楼梯间和相邻楼层空气压力之间的设计压差。这些规范是针对静态、稳态（操作）而定义的。有时还规定了在使用楼梯间门时补充空气的补偿机制。由于缺乏测量因楼梯间门打开而导致的楼梯间空气污染的技术，因此尚未制定与乘员相关的性能测量。由于可维持性分析的进展，现在可以计算由于烟雾渗透而在空气空间中产生的可维持性。该项目的结果可用于分析楼梯间中流行的烟气控制技术的性能。 主要研究人员:John H.Klote，John H.Klote，Inc.进行时间:2001年6月至2002年6月赞助人:TC 5.6，火灾和烟雾控制

Traditional techniques for stairwell pressurization have been prescriptive in nature, based primarily upon maintaining a design pressure differential between stairwell and adjoining floor air pressures. These specifications are defined for static, steady state (operation). Sometimes compensatory mechanisms to supplement air during use of stairwell doors are specified as well. No occupant related performance measures have been developed due to the lack of techniques for measuring stairwell air contamination resulting from opening of stairwell doors. Because of advances in tenability analysis, it is now possible to calculate resulting tenability in air spaces due to smoke infiltration. The results of this project can be used to analyze the performance of popular techniques for smoke control in stairwells.Principal Investigator: John H. Klote, John H.
