Fire Safety Concern for Supertall Buildings 超高层建筑的消防安全问题
远东地区建造了许多超过984英尺(300米)高的超高层建筑。他们的消防系统只遵循为高层建筑设计的现行规范。人们担心超高层建筑的消防安全规定是否足够。然而,很少有人对超高层建筑房间火灾的动力学进行全面的研究。超高层建筑中的火灾会受到风的作用,并有很高的热释放率;本文将讨论它们的特点。首先回顾超高层建筑火灾的一般情况。接下来,我们将介绍超高层住宅中燃烧可燃物的热释放率。将估算超高层建筑中的烟囱效应。 将参考三个不同城市的气候条件。本文还将讨论提供适当楼梯增压系统的必要性。引用:ASHRAE论文CD:2014 ASHRAE冬季会议,纽约
Many supertall buildings that are over 984 ft (300 m) tall have been constructed in the Far East. Their fire protection systems only follow the current codes that are designed for tall buildings. People are worried whether fire safety provisions in supertall buildings are adequate. However, very few comprehensive studies on the dynamics of room fires in supertall buildings have been conducted. Fires in supertall buildings are subject to wind action and have a high heat release rate; their characteristics will be discussed in this paper. General aspects of supertall building fires will be reviewed first. Next, the heat release rate of burning combustibles in a supertall residential flat will be presented. The stack effect in supertall buildings will be estimated. The climatic conditions of three different cities will be used as references. The paper will also discuss the necessity of providing appropriate staircase pressurization systems.
