The wind tunnel experiment,project argument,structure calculation analysis, calculation of the joint bearing capacity, calculation and experiment of the support-joint load carrying capacity of a super-span stretched stereoscopic steel pipe trussing are introduced- A normal usage period of the project after it had been built indicates that the major trussing and the supporting structure below have enough bearing capacity and deformability, and meet the demands of design code and actual usage.

摘要］介绍了某超大跨度伸臂立体管桁架结构的风洞试验、方案论证、结构计算分析、节点承载力验算、支座节点承载力验算和试验等。该结构建成后一段时期的正常使用表明，工程的主体桁架和下部承力结构具备较强的承载变形能力和可靠的安全度，满足设计规范和实际使用要求。
