A series of problems on fire simulation of performance-based fire protection design and assessment of large shopping centre are studied such as fire load, fire scenarios, heat release rate, smoke evacuation and air supply, author's experience of application of fire development model FDS (Fire Dynamics Simulator) and CFAST (Consolidated Model of Fire Growth and Smoke Transport) and indeterminate question analysis etc.
本课题研究了商业建筑性能化防火设计与评估的火灾模拟方面的系列问题:设计火荷载、火灾场景设定、热释放速率(HRR)设定、商场性能化防火设计的排烟与补风、火源发展模型、火灾模拟软件FDS(Fire Dynamics Simulator)、CFAST(Consolidated Model of Fire Growth and Smoke Transport)应用体会、商场火灾模拟的不确定性问题分析等。
According as the research on performance-based fire protection design and assessment in chapter 2 and 3, a large shopping centre case is studied in chapter 4 by applying FDS, CFAST and ESAFETY simulation software.
Through application of Code for fire protection design of buildings GBJ16-87(version in 2001) and Code for fire protection design of tall buildings GB50045-95(version in 2001) in working,this paper summarizes and analyzes the design of fire compartment for buildings,and discusses the design of fire compartment for big space buildings and underground buildings and detail structure from view of practice.
Combine with the reasonable thinking of the high-laye r building safety disperses design in actual working. This paper discusses about the arrangement of the safety disperses facilities in the high-layer building s afety disperses system according to the <Fire Protection Design of Tal l Buildings >>GB50045-95 (version in 2001), in order to consult in the work of d esigning.
Also discusses the fire resistant design ideas of the steel structure from many aspects such as the fire model of steel structured building, external application of non combustibles on the main load bearing elements, consolidation of the load bearing elements as wellas building fire protection design etc. Finally, it discusses the tendency of the fire protection design in large space steel structure.
This paper synthesizes the experimental and theoretical conclusions about the fire protection researches in steel structures and steel- concrete composite structures. The fire protection design methods in the steel- concrete composite structures are summarized, and a comparison with the fire protection design methods in steel structures is made. Some suggestion about the fire- resistance designs in the steel- concrete composite structures is presented thereby.
