Analysis and Design of Large-span Multi Wave Folded-plane Spatial Steel Grid Structure for the Service Building of Yinan Jiehu Park
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.
