在建筑火灾期间，楼梯间的烟雾记录可能会产生严重后果。开展了一个项目，以研究一个或多个未正确支撑的打开楼梯间门对楼梯间和建筑内其他位置的可维持性条件的影响。本项目使用网络建筑流模型CONTAM和区域火灾模型CFAST分析了高层建筑中的80种烟气传输场景。可维持性计算由专门为此编写的计算机程序执行。这一基本方法已用于许多其他应用，是分析高层建筑火灾烟气传输的唯一实用方法。然而，这种分析方法还有很多需要改进的地方，需要开发软件来更真实地模拟大型高层建筑火灾中的烟气传输。分析中包括的参数包括天气、楼梯几何结构、建筑渗漏、封闭式电梯大堂、电梯通风、楼梯加压系统、火灾类型、火灾位置和打开楼梯门的布置。 单位:双引文:研讨会论文，加利福尼亚州阿纳海姆，2004年

During building fires, smoke logging of stairwells can have serious consequences. A project was conducted to study the consequences of one or more improperly propped open stairwell doors on tenability conditions in the stairwell and at other locations in the building. This project used the network building flow model CONTAM in conjunction with the zone fire model CFAST to analyze 80 smoke transport scenarios in high-rise buildings. Tenability calculations were performed by a computer program that was specifically written for this purpose. This basic approach has been used for a number of other applications, and it is the only practical approach to analyze the smoke transport due to fires in high-rise buildings. However, the method of analysis leaves much to be desired, and software needs to be developed to more realistically simulate smoke transport from fires in large high-rise buildings. Parameters included in the analyses are weather, stair geometry, building leakage, enclosed elevator lobbies, elevator vent, stair pressurization systems, type of fire, location of fire, and arrangement of open stair doors.Units: Dual
