ISO/TR 12471:2004回顾了在测量和理解结构材料在高温、物理和机械特性变化方面如何响应火灾方面取得的进展，并确定了需要进一步工作以生成所需数据的领域。传热分析方法与力学模型相结合，以计算实际火灾和ISO标准炉加热条件下从单个元件到完整框架的结构行为。ISO/TR 12471:2004回顾了计算分析的进展，并指出了如何将其与概率分析结合使用，为结构消防工程设计提供基于风险的方法。

ISO/TR 12471:2004 gives a review of the advances that have been made in measuring and understanding how structural materials respond to fire in terms of changes in their elevated temperature, and physical and mechanical characteristics, and to identify areas where further work is necessary to generate the data required. Analytical methods for heat transfer are combined with mechanical models to calculate structural behaviour from single elements up to complete frames under real fire and ISO Standard furnace heating conditions. ISO/TR 12471:2004 reviews advances in computational analysis and indicates how these can be used with probabilistic analysis to provide a risk-based approach to structural fire engineering design.
