1. Design of steel structure aircraft hangar:

1). The span and height of the hangar are relatively large. Generally, the span of a large aircraft hangar is more than 62m, and the height is about 20m. The span of a medium-sized aircraft hangar is also more than 42m.
2). To meet the aircraft requirements entering and exiting the hangar, the front of the hangar has a large opening and no pillars. The structure of the gate opening is a critical issue in the design of the large-span hangar structure.
3). To meet the hangar’s use requirements, the roof is required to have greater rigidity. In large wind loads, such as adopting a light roof system, engineers must consider the influence of wind suction on the structure when the door opened.

2. Structure of the aircraft hangar:

The plane layout and height requirements of the aircraft hangar are unique, which directly affects the structure of the building.
Due to the vast span of the hangar, the weight of the roof structure in the total load is significant. The steel structure has the advantages of high strength, lightweight, small cross-section. Therefore, steel structures generally used as load-bearing roof systems for large-span buildings, which can reduce the weight of the roof structure and reduce costs.

3. Fireproof design

The hangar has ample space, and many aircraft often maintained inside the building. So there are various maintenance equipment and working platforms accompanied by explosive sources of oil and gas combustion. There should be strict requirements and perfect facilities for fire and explosion protection. Currently, high-foam foam fire extinguishing systems mostly used.

The hangar door has a unique structure due to its large size and weight, and it needs to be easy to open. To make it easier for planes to enter and exit the hangar, the door usually designed according to the full height of the aircraft hangar. The total length divided into several fans, each of which is about 10-20 meters wide. There is a dedicated guide structure on the top of each door, and the bottom track wheel supports the door leaf, the door leaf made of the steel frame covered with a thin steel plate, the thickness of the door leaf about 500-700 mm.
