标准范围

ISO/TR 24679-6:2017提供了将ISO 24679-1应用于办公楼的消防安全工程设计示例。在ISO/TR 24679-6:2017中，对建筑物进行了整体结构分析。它包括对八层混凝土建筑在火灾中的结构性能进行数值评估。进行该分析是为了证明，由于发生火灾时建筑物的结构行为，相关设计火灾场景的消防安全目标符合结构安全试验计划。关于这一点，研究了一场充分发展的火灾。本文件的目的是使用ISO 24679-1评估发生火灾时公众完全可进入的办公楼的性能。在这方面，使用详细的火灾模型识别和分析了一场关键设计火灾。然后使用有限元模型对关键设计火灾进行了更详细的分析。高级模型提供了分析给定建筑环境消防安全所需的所有综合信息。需要注意的是，本文件仅涉及火灾期间与结构性能相关的消防安全目标。因此，本文件中的分析只是整个建筑消防安全策略的一部分。

ISO/TR 24679-6:2017 provides an example of fire safety engineering design in the application of ISO 24679？1 to an office building.In ISO/TR 24679-6:2017, an overall structural analysis of a building is undertaken. It consists in a numerical assessment of the structural performance of an eight-storey concrete building when subjected to a fire. This analysis is performed in order to demonstrate that the fire safety objectives, for the relevant design fire scenarios, due to structural behaviour of building in the event of fire, are met with the trial plan for the safety of structure. With regards to this, a fully developed fire was studied.The purpose of this document is to assess the performance of an office building which is fully accessible to public in case of fire, using ISO 24679？1. In this respect, a critical design fire was identified and analysed using detailed fire modelling. A more detailed analysis was then performed for critical design fire using the finite element model. The advanced model provided all the comprehensive information necessary for analysing the given built environment with respect to fire safety.It is to be noted that this document only addresses the fire safety objectives related to the structural performance during fire. The analysis within this document is therefore only part of the overall building fire safety strategy.
