摘　　要：以实际工程项目为例,探讨多波折面空间钢网格结构体系在大跨度结构中的应用。对项目进行重难点分析,选取折面空间钢网格结构体系,运用YJK和SAP2000软件进行弹性对比计算,采用YJK软件进行屈曲分析以及静力弹塑性分析,对该结构体系的动力特性、受力特点、稳定承载力等进行分析与研究。对分支柱结合柱脚进行综合设计,并对结构细部节点进行有限元应力分析。分析发现,该体系具有类似于桁架的受力特点和设计控制荷载。分析结果表明,合理设计条件下该结构体系适宜用于大跨度结构且具备足够的安全性,具有一定的推广价值。设计过程中采用的分析方法和细部设计措施可以为类似建筑工程提供参考。An actual project is taken as an example to explore the application of a spatial steel grid structure system in large-span structures,Selecting the folded-plane spatial steel grid structure,the key and difficult points of the project is analyzed,YJK and SAP2000 software are used for elastic comparison calculation,YJK software are used for buckling analysis and static elastic-plastic analysis.The dynamic characteristics,stress characteristics and stable bearing capacity of the structural system are analyzed and studied.Comprehensive design of branch columns combined with column bases and finite element stress analysis of structural detailed nodes.Through analysis,it is found that the structural system has similar stress characteristics and loads to trusses.The analysis results show that under reasonable design conditions,the structural system is suited for large-span structures and has sufficient safety,which has certain promotion value.The design methods and detailed construction measures adopted in the design process can provide reference for similar building projects.
