现代木结构建筑具有结构体系明确、传力路径清晰、用材固碳环保和综合功能优越等特征,是3大装配式建筑形式之一,在国外发达国家和地区应用广泛.相较于其它建筑结构体系,木结构建筑具有突出的节能减碳效果,因此,近年来在我国的科学研究和工程应用领域日益受到重视.文章主要通过分析全球木材资源供给情况,系统阐述限制我国现代木结构发展的抗火性能研究现状,建议从加强宣传引导、着力资源保障、抗火性能提升和技术创新4个层面入手,旨在推动现代木结构在我国的可持续发展和规模化工程应用.
Modern timber structures,one of the three main prefabricated buildings,are widely used in developed countries and regions abroad because of their clear structural system and transmission path,carbon fixation and environmental protection with materials,and superior comprehensive functions.Recent years have seen a rise in interest in timber structures in China because of their exceptional ability to reduce carbon emission and save energy when compared to alternative structural solutions.The availability of wood resources worldwide is examined,and the state-of-the-art of fire resistance is primarily discussed in this paper,which is a factor limiting China's ability to build contemporary timber structures.In order to support the sustainable development and widespread engineering application of modern timber structures in China,it is advised to improve public awareness and guidance,boost resource guarantee,and innovate key technology research and development.
