［摘要］介紹了某超大跨度伸臂立體管桁架結(jié)構(gòu)的風(fēng)洞試驗(yàn)、方案論證、結(jié)構(gòu)計(jì)算分析、節(jié)點(diǎn)承載力驗(yàn)算、支座節(jié)點(diǎn)承載力驗(yàn)算和試驗(yàn)等。該結(jié)構(gòu)建成后一段時(shí)期的正常使用表明，工程的主體桁架和下部承力結(jié)構(gòu)具備較強(qiáng)的承載變形能力和可靠的安全度，滿足設(shè)計(jì)規(guī)范和實(shí)際使用要求。

［關(guān)鍵詞］超大跨度伸臂矩形立體管桁架；風(fēng)洞試驗(yàn)；節(jié)點(diǎn);預(yù)應(yīng)力; 型鋼混凝土；斜柱

Abstract: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.

Keywords:super-span stretched stereoscopic steel pipe trussing; wind tunnel experiment; joint; prestressed; composite steel and concrete; diagonal column
