摘　　要：木材作为建筑材料在生产过程中可以达到零碳甚至负碳的效果,随着我国森林资源的恢复以及与森林资源丰富的国家间贸易合作的加深,合理地利用木结构是我国建筑业实现“碳中和、碳达峰”目标的有效手段之一.本文回顾了钢木空间结构在国内外的工程应用实例,分析总结了木材本构关系和钢木节点的研究现状,对钢木空间结构的材料本构、结构稳定分析和高性能节点等有待进一步开展的研究工作提出展望.Timber,as a sort of construction material,can achieve the goal of zero even negative carbon emission during its manufacturing process.Utilizing timber structures properly is an important method to achieve the target of“carbon neutralization”and“emission peak”,as the recovery of forest resources in China and the growth of import from countries with rich forest resources.Typical construction applications of steel-timber structures in China and around the world are reviewed in this paper.Current research on the constitutive relation and steel-timber joints are also summarized.The research prospects of timber steel-space structures,incluling constitutive relation,structural stability analysis and high-performance joint,are proposed in the end.
