World’s longest-span aircraft hangar in Beijing Daxing International Airport got its last roof structure on Monday 3 September 2018.
Weighing 7,200 tons, the 404.5-meter-long and 97.5-meter-wide roof truss was mostly pre-assembled on the ground and then elevated to a height of 38.5 meters after three rounds of roof raisings, reported local media
The structure also brought the benefit of saving steel consumption. “At least 100 million tons of steel would be used if the roof were not built with a W-truss structure. But we only used 7,200 tons of steel, maybe the lowest amount in building equal-sized hangars,” said Hong Biao, a project manager from Beijing Construction Engineering Group involved in the construction.
Covering an area of 390,000 square meters, or about the size of five football fields, the long-span hangar can hold a maximum of 12 aircraft, including two A380 jumbos, three Boeing 777 wide-body aircraft and seven narrow-bodies.
The new airport is expected to start trial operations in October 2019.
