摘　　要：文章以南京无线谷紫金山实验室为背景介绍其结构方案设计。紫金山实验室是国家级重点实验室,由于其特殊的建筑功能需求,存在着各种大空间暗室,在结构上表现为多层通高、高位转换等。经过各种结构方案设计研究比较,最终采用受力合理的屋顶吊挂桁架的方案,通过矩形钢管混凝土柱和屋面钢梁刚接的方案来减少计算长细比,从而解决柱子长细比超限问题,同时通过合理布置斜撑来调整整体方案的平面不规则情况。最后采用了钢结构框架-部分支撑-屋顶吊挂桁架的结构体系。This Paper is based on the design of structure schemes about Zijin Mountain Laboratory in Nanjing Wireless Valley.Zijin Mountain Laboratory is the national key laboratory.Because of the special requirements of various darkrooms,there are various large spaces such as high-pass and conversion in Zijin Mountain Laboratory.Through the design and study of structure schemes,suspended truss on roof and rectangular concrete-filled steel tubular column are adopted to shorten the calculation of slenderness ratio,and the diagonal braces are reasonably arranged to adjust the irregularity of the whole structural scheme.Finally,the structural system of steel frame,partial braces and suspended truss on roof is adopted.

关 键 词：屋顶吊挂桁架 矩形钢管混凝土柱 结构转换层 通高
