和低层建筑相比,高层建筑自身特点增加了其潜在火灾发生概率、损失的严重性和多样性。这些固有特性包括:较高的居住荷载、较长的疏散时间、消防机构灭火救援通道的问题、潜在的水压问题/可用性问题、显著的烟囱效应、可能多种情况同时出现,以及它们标志性的、高度引人注目性的特点。在高层建筑的设计过程中详细说明充分的烟控措施对于解决上面的问题起着非常关键的作用。广义上来讲,“烟气控制”就是通过主动或者被动措施来控制整个建筑中烟气的流动。对受保护的开口处安装防火隔墙和挡烟板是一种被动的烟控措施。也可以说自动喷水灭火系统是一种烟控措施,它能够限制火灾蔓 Compared with the low-rise buildings, high-rise buildings themselves increase the probability of potential fire damage, the severity and diversity of losses. These inherent features include: higher occupancy loads, longer evacuation times, problems with fire-fighting facilities fire-fighting aisles, potential hydraulic problems / availability issues, significant chimney effects, possible simultaneous occurrences, and their signature Highly eye-catching features. The detailed design of smoke control measures in the design of high-rise buildings plays a crucial role in solving the above problems. Broadly speaking, “flue gas control ” is through active or passive measures to control the flow of flue gas throughout the building. Installation of fire barriers and smoke barriers on protected openings is a passive smoke control measure. It can also be said that sprinkler system is a smoke control measures, it can limit the fire manure
