Summary: | 碩士 === 中央警察大學 === 消防科學研究所 === 100 === With high-rise buildings appearing densely in urban areas, various researches on how to prevent fire spread have been developed in several countries. Window flames could not only damage the vertical structures, but also harm the stability of structural elements in compartment fires. Once igniting the combustible materials of the upper floors, the flame may break the upper windows, even cause fire spread, and make the adjacent buildings burned by flame contact or radiation. For example, the fire occurred at apartment buildings in Jiaozhou Road, Jing'an District, Shanghai city, China, on November Fifth, 2010, caused 58 people dead and more than 70 people injured. Therefore, this study investigates the influences of different space factors on the apartment fire and evaluates their harmful impact on the bulidings. The aim of this study is to find how to prevent fire spread and ensure life safety.
With the aid of FDS, this study will analyze the influences of different space factors on the compartment fire. Relevant factors include inside fuel properties, the rate of heat release, materials of external wall, the shape factor, the ventilation factor, and the spandrel depth, balcony and Ad’s depth and geometry, opening or closing doors, etc. By utilizing Surfer 8.0, simulation results can be analyzed to understand how the space factors affect the behavior of window flames. Finally, setting up the related parameters to simulate scenarios of bedroom fire and living room fire, and analyzing the results we know that HRR increase, wide windows and Steel-FIB construction could let window flames close to external wall and increase its destruction. Some suggestions and strategies for improving building management and rescuing safety are proposed.
