摘要
轻型木结构材料由于其箱型结构体系的特性,兼具木结构绿色环保等特点,同时具有更高的强度和耐火性能,近年来使用较为普遍。因此,对轻型木结构材料的火灾危险性及耐火性能进行了理论分析,对火灾情况下的轻型木结构和混凝土结构进行了模拟比较。研究发现,由耐火石膏板覆盖、不燃材料填充的轻型木结构建筑在耐火极限内,具有与混凝土建筑相当的安全性和可靠性。
Light wood structure materials are widely used in recent years due to the characteristics of their box structure system,both green and environmental protection of wood structures,and higher strength and fire resistance.Therefore,the fire hazard and fire resistance of light wood structure materials are theoretically analyzed.And the simulation and comparison of light wood structures and concrete structures under fire conditions are carried out.The study found that light wood structures covered by refractory gypsum board and filled with non-combustible materials have the same safety and reliability as concrete buildings within the fire resistance limit.
