摘要
首都机场306m长的飞机库是世界上最大的机库之一,跨度为153+153m,屋盖结构采用了三层四角锥网架与大跨度栓焊钢桥相结合的形式。本文主要论述了屋盖结构形式、节点设计、抗震设计、焊接质量标准及保证措施、屋盖的整体提升等有关问题。
The 306×90m hangar of Capital Airport is one of the largest hangars in the world. The roofstructure consists of three-layered pyramidal space grids together with a bolted and weldedtwospan (153 + 153m) continuous steel bridge over the hangar gate. This paper describes the type ofthe roof structure, node design, seismic design, quality standard and assurance measures taken forwelding work as well as for lifting process of the roof.
