Performance-based Design Of High-rise Buildings Of The Fire Load

Fire load is the heat of the combustible materials per unit area. Fire protectiondesign fire load is the most basic and the most important data is one of the stages ofdevelopment of a comprehensive fire performance of the basic elements of fire load isfire scenario underlying data. Fire scenario building performance based fire safetydesign is the design and performance evaluation of fire safety an important part of theanalysis, with the rapid social and economic development, and performance-based firesafety design in China has been rapid development and application, however, about thefire scene most of them are designed with reference to foreign data, mainly due to thefire load of domestic lack of basic data. Thus, this paper carried out a field survey,completed the pre-construction fire load database and the findings of the fire loadapplied to the design of the fire scene, and then evaluate the performance of the buildingdesign, has important practical significance.Thesis on the analysis of domestic and fire load and fire scenarios related research,based on field research and literature references through a combination of methods,statistical analysis of Chongqing City high-rise office buildings and shopping malls fireload basic data, the office type building and shopping malls fire load distribution. Thefindings show office room fire load density is normally distributed, and shops and thefire load density lognormal distribution. Room fire load density has a relationship withthe room employ. Integrated class office fire load density maximum is560.78MJ/m2.Commercial buildings and Cloth shop fire load density maximum is676.48MJ/m2. Thefood and beverage outlets and watches jewelers fire load density are small. Statisticsoffice buildings and shopping centers in the fuel value of the proportion of combustiblematerials.Based on the findings of fire load, analyze fire scenarios associated with firegrowth coefficient and the maximum heat release rate. Access complete use of high-risebuilding fire load Chongqing database pre-construction, analysis of the database systemimplementation process. According to the findings of the fire load and fire scenariostudies, the use of fire and smoke evacuation Pathfinder FDS software and softwarearchitecture typical for the performance-based fire design studies. When a sprinklersystem and smoke control systems can work in the case, to ensure the safe evacuation.
