| 摘 要： | 由于采用大空间的建筑布局以及可燃物的特殊性,现有规范方法难以满足河南省新广播电视塔防火设计安全性与经济性要求。基于性能化设计思想对该工程全景画馆钢结构体系的抗火安全性进行了评估。确定结构抗火性能目标,对结构整体在可能最不利火灾场景下的力学性能进行分析,根据结构的受火性能是否满足抗火性能目标来评估结构的抗火安全性及需要采取的防火保护措施。在此基础上对整个塔体结构的安全性进行了分析,其成果可为国内外高层钢结构的整体抗火分析提供借鉴和参考。

| Abstract: | For the large space and the especial combustible,the exited codes can not be used for the fire safety design of a high-rise steel TV transmission tower.A newly integrated method of fire-structural coupling analysis was introduced to analyze the overall fire safety behavior of panoramic painting gallery under fire conditions based on the performance-based fire design ideas.The target of structural fire resistance was determined.The behavior of structural members of panoramic painting gallery was analyzed in ... |
