Abstract:According to the feasibility study and consultancy service for a large span hangar which is to be built, several kinds of structural schemes were analyzed. The hangar is composed of a maintenance hangar and a painting hangar. The span is (147+72.5)m and the depth is 83m. Concept and detailed analysis were proceeded according to the possible structural style，including truss string structure, cable-bracket style, inclined cable structure, arch truss structure, principal-secondary truss, arch truss structure and grid structure，then the advantage and disadvantage of all these structural styles were pointed out. According to the design conditions and technical conditions，computations and optimizations were proceeded to the lagging structure and grid structure，and steel consumption was given.
Keywords:large span hangar； structural scheme analysis； steel consumption
