基于性能化防火设计的方法,以自然排烟量等于烟气产出量为基本要求,利用火灾烟气模型和火灾动力学理论,计算出高大空间建筑火场烟气各物性参数,较系统的提出了大空间建筑的自然排烟系统开窗面积的理论计算方法。以某室内商业步行街为例,理论计算分析了不利火灾场景下烟气流动和排烟效果,该建筑现有排烟口面积满足排烟要求。
基于性能化防火設計的方法,以自然排煙量等于煙氣產齣量為基本要求,利用火災煙氣模型和火災動力學理論,計算齣高大空間建築火場煙氣各物性參數,較繫統的提齣瞭大空間建築的自然排煙繫統開窗麵積的理論計算方法。以某室內商業步行街為例,理論計算分析瞭不利火災場景下煙氣流動和排煙效果,該建築現有排煙口麵積滿足排煙要求。

Based on performance-based fire safety design, as the basic requirements of the smoke natural emission equal to the flue gas volume of output, use of fire smoke model and fire dynamics theory, calculate the physical parameters of fire flue gas in the large space building, put forward systematic theoretical calculation method on the fenestration area of natural smoke exhaust system in the large space. An indoor commer- cial walking street as example, by theoretical calculation, analysis of flue gas flow and smoke exhaust effects under the adverse fire scene, the existing exhaust port area of the building meet the exhaust requirements.
