| 摘 要： | 为了解决现行防火设计规范中门式刚架钢结构经济性、科学性相对较低的问题,对门式刚架钢结构进行了火灾下整体力学性能分析,建立了一系列具有典型跨度、高度的门式刚架结构模型,对火灾燃烧1 h过程中结构的受力性能进行了计算和分析,得到了门式刚架结构火灾下应力和变形的变化规律及其破坏模式,并结合现实火灾实例对围护结构在火灾下对结构力学性能产生的影响进行了讨论.

| Abstract: | To deal with the problem of relatively low level specified, both economically and scientifically, in current fire protection and prevention regulations, its global mechanical properties of the portal frame steel structure were studied analytically in the fire disaster, models with typical spans and heights were established for a series of portal frame structures and their mechanical properties were analyzed numerically during the 1 h burning process in the fire disaster, from which the failure modes and the... |
