What are the common structural forms of aircraft hangars?
Aircraft hangars are special large-span steel structure buildings . The main design challenges are the ultra-large column-free clearance, structural stability, and resistance to wind and snow. There are three main types of hangar structures on the market: portal frame, bolted ball structure, and tubular truss. These three types differ significantly in their load-bearing principles, span capacity, cost, and applicable scenarios, which are also the main basis for hangar scheme selection, budget control, and construction implementation (design should follow local standards, such as EU Eurocode, US IBC, etc., specific local standards prevail). 1. Portal Frame Structure Structural Principle: A portal frame is a rigidly connected steel column and beam structure forming an integral portal frame, belonging to a planar load-bearing structure. The load is directly transferred to the steel columns and foundation through the roof steel beams. The system is simple, the force transmission is clear, ...
