摘　　要：清华大学经济管理学院教学科研楼空中连廊三层整体传递到独柱荷载达70000 kN,两侧和主体相连,悬空部分采用独柱支撑,跨度大且双向悬挑,独柱的承载力,刚度、节点抗震等要求高,经研究采用多项关键技术,高质量地完成了大截面钢管擎天独柱的施工。The teaching building of the School of Economics and Management,Tsinghua University,of which 3-storey overpass corridor passes 70000 kN load onto the single column and both sides are connected to the main building.The cantilever part of the overpass corridor is supported by one single column and has large-span and double-direction cantilever.There are high requirements for the single column’s bearing capacity,rigidity and node seismic resistance.Multiple key techniques were adopted to successfully complete the construction of super-high large-section steel tube column.
