国家大剧院钢壳体施工支撑体系的结构选型与设计

Types Choice and Optimization Design for the Construction Support System of the National Grand Theatre Domes Shell

国家大剧院巨型钢壳体安装过程中使用螺栓球网架结构代替普通脚手架作为其临时施工支撑体系 ,充分发挥了网架结构的空间受力性能 ,而且装卸方便 ,可以重复利用。由于该工程体量高大 ,支撑条件复杂 ,针对工程需要 。

Bolted spherical jointed space truss structure is applied in erection engineering of the National Grand Theatre Dome Shell as temporary construction support system instead of currently construction false work.The space truss structure can be erected and disassembled conveniently and the structure materials can be reused.Based on the engineering load and support conditions,this paper researches the rational types choice and structure design.
