Fire following earthquake can cause substantially loss of life and property, added to the destruction already caused by the earthquake, and represents an important threat in seismic regions. On the other hand, even when no fire develops immediately after an earthquake, the possibility of later fires affecting the structure must be adequately taken into account, since the earthquake induced damages make the structure more vulnerable to fire effects than the undamaged one. The paper presents the evaluation of the fire resistance time for some unprotected steel moment resisting frames, in the hypothesis that they are already damaged by the earthquake, using advanced methods for earthquake and subsequent fire analysis, and using both standard and natural fire scenarios. Moderate and severe seismic actions are used for designing the steel structures. The influence of the damage level induced by the earthquake on the fire resistance is emphasized.

钢制抗弯框架地震分析后的火灾

地震后发生的火灾可能会造成重大生命和财产损失，加之地震已经造成的破坏，并在地震地区构成重要威胁。另一方面，即使地震后没有立即发生火灾，也必须充分考虑到以后发生火灾影响结构的可能性，因为地震引起的损坏使该结构比未损坏的结构更容易受到火灾的影响。本文提出了一些不受保护的钢制抗弯框架的耐火时间的评估，假设它们已经被地震破坏，使用先进的地震方法和随后的火灾分析，并使用标准和自然火灾场景。中度和强烈地震作用用于设计钢结构。
