Abstract

Automated Rack-Supported Warehouses (ARSWs) are a particular type of steel racks that combine the structural efficiency of steel construction with automated machines for handling stored products.

This work addressed the fire development in ARSW, by investigating the fire modelling which can be used in a multi-depth ARSW structure, by adopting zone models, and Computational Fluid Dynamics (CFD) ones. Since the traveling fire plays a key role in these peculiar structures, a simplified “multi-cells” fire model that allows vertical and horizontal propagation, is proposed.

Starting from the results of an extensive experimental campaign, available in the literature, conducted on steel racks, criteria to evaluate the vertical and horizontal propagation times are provided. Finally, the criteria of the simplified fire model were also compared with the results of advanced CFD analyses, in which the traveling fire was naturally considered, showing a good agreement. This proposed “multi-cells” zone model provides a useful tool for both design and assessment of the fire behaviour of ARSW structures.

火灾传播模型对钢架结构元件温度的影响

自动化货架支撑仓库（ARSWs）是一种特殊类型的钢货架，它结合了钢结构的结构效率和处理存储产品的自动化机器。通过采用区域模型和计算流体力学（CFD）模型，研究了可用于多深度ARSW结构的火灾模型，解决了ARSW的火灾发展问题。由于行进的火在这些特殊结构中起着关键作用，因此提出了一种允许垂直和水平传播的简化“多单元”火模型。从文献中广泛的实验活动的结果出发，在钢架上进行，提供了评估垂直和水平传播时间的标准。最后，将简化火灾模型的准则与先进的CFD分析结果进行了比较，其中自然考虑了移动火灾，结果吻合较好。提出的“多单元”区域模型为设计和评估ARSW结构的防火性能提供了一个有用的工具。

期刊介绍： Fire Safety Journal is the leading publication dealing with all aspects of fire safety engineering. Its scope is purposefully wide, as it is deemed important to encourage papers from all sources within this multidisciplinary subject, thus providing a forum for its further development as a distinct engineering discipline. This is an essential step towards gaining a status equal to that enjoyed by the other engineering disciplines.
