摘　　要：首先对适合于大跨胶合木结构常见结构体系的结构构成、受力特点、适用范围进行了分析,包含木桁架结构、木网架结构、木网壳结构、木拱结构以及木张弦结构等大跨胶合木结构体系。然后通过青岛胶东国际机场航站楼指廊屋盖胶合木结构等4个实际工程项目探讨了大跨度胶合木结构选型和结构设计,对比了不同结构方案力学性能指标、木材用量指标。最后针对大跨胶合木结构设计还需要进一步完善的问题,如木材本构模型、节点分析、蠕变和湿度影响以及整体稳定分析等进行了讨论。Firstly, the structural composition, force characteristics and application scope of the common structural systems suitable to large-span glulam structures were analyzed, such as wooden truss structures, wooden lattice structures, wood grid shell structures, wooden arch structures and wooden stringed structures. Then the selection of structural typology and structural design of four large-span glulam engineering projects have been introduced, including the glulam structure of the corridor roof of the terminal building of Qingdao Jiaodong International Airport and so on, and the mechanical performance indexes and wood consumption indexes of different structural schemes were compared. Finally, the issues that need to be further improved in the design of large-span glulam structures were discussed, such as wood constitutive model, node analysis, effect caused by creep and humidity, and overall stability analysis.
