ISO TR-24A/PD-2015提供了与防火工程相关的安全应用 根据ISO/TS 24679中给出的方法对开放式停车场进行评估。这份报告 描述所采用的过程，该过程遵循的步骤与中给出的步骤相同 ISO/TS 24679。本技术报告的附件给出了详细的数值分析结果 根据本特定消防安全工程程序，在最严重的火灾情况下获得 开放式停车场。消防安全工程应用于开放式停车场，就其耐火性而言， 考虑特定的设计火灾场景以及相应的火灾发展。它考虑了 局部加热、整体结构行为，而不是单个结构构件阻力等。 事实上，如果露天停车场发生火灾，只有一小部分结构直接暴露在火灾中 由于开放环境以及消防队的快速干预，火势蔓延有限。在里面 因此，可以考虑将载荷重新分配到冷部件 通过全球结构分析。这种基于复合地板力学响应三维建模的方法是可行的 已在法国的各种消防安全工程项目中使用，用于检查未受保护设备的稳定性 复合钢框架露天停车场可能会发生最严重的实际火灾。最后，应该提到的是，这些严重火灾场景已被选为耐火材料 只是目的而已。例如，它们不应用于烟雾控制目的。 交叉引用:ISO/TS 24679:2011EN 1990:2002EN 1991-1-2:2002EN 1992-1-2:2004EN 1994-1-1:2004EN 1994-1-2:2005购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS PD ISO/TR 24679-3:2015 provides a fire safety engineering application relative to fire resistance assessment of an open car park according to the methodology given in ISO/TS 24679. This report describes the adopted process which followed the same step by step procedure as that given within ISO/TS 24679. The Annexes of this Technical Report presents the detailed numerical analysis results obtained for most severe fire scenarios on the basis of this specific fire safety engineering procedure for open car parks.The fire safety engineering applied here to open car parks, with respect to their fire resistance, considers specific design fire scenarios as well as corresponding fire development. It takes account of localized heating, global structural behaviour rather than single structural member resistance, etc.In fact, in case of fire in open car parks, only a small part of structure will be exposed directly to fire because of the limited fire spread due to open environment as well as rapid fire brigade intervention. In consequence, the load redistribution to cold parts might become possible and can be taken into account through global structural analysis.This kind of approach based on 3D modelling of the mechanical response of composite floor was already used in various fire safety engineering projects in France to check the stability of unprotected composite steel framed open car parks subject to most severe real fire scenarios.Finally, it should be mentioned that these severe fire scenarios have been selected for fire resistance purposes only. They should not be used, for example, for smoke control purposes.Cross References:ISO/TS 24679:2011EN 1990:2002EN 1991-1-2:2002EN 1992-1-2:2004EN 1994-1-1:2004EN 1994-1-2:2005All current amendments available at time of purchase are included with the purchase of this document.
