| 摘 要： | 采用耐火试验炉对装配式模块建筑四柱组合的钢结构构件开展不同防火保护条件下的试验研究，分析了模块建筑组合钢柱在火灾下的试验现象、升温曲线、变形特点及破坏形态，获取了模块建筑组合钢柱的耐火极限，以此对模块建筑组合钢柱的防火保护构造提出了设计建议。结果表明：8 mm厚的组合钢柱构件，在双层20 mm高性能防火石膏板的保护下，耐火极限不低于2.50 h，满足二级耐火等级建筑要求；在双层12 mm厚纤维增强硅酸板和60 mm厚岩棉的保护下，耐火极限不低于3.00 h，满足一级耐火等级建筑要求；在三层高性能防火石膏板（15 mm+20 mm+20 mm）的保护下，耐火极限不低于4.00 h。

| Abstract: | Fire
resistance tests were carried out to study the fire performance of 4-assembled
steel columns used in prefabricated modular buildings with different fire
protection methods.The experimental phenomena, temperature curves, deformation
curves and failure modes of the assembled steel columns were analyzed, and the
fire resistance ratings were obtained. Suggestions on fire protection of
assembled steel columns used in modular building are given in order to satisfy
the fire-resistance rating requirements in the fire code. |
