Asiana Airlines, one of the leading Korean carriers, evolve their business at the Incheon International Airport by a new hangar for maintenance of Boeing 747 aircrafts. An expressive design consisting of an arch structure extended by wings on both sides is planned as the airline’s landmark. All two-and-a-half-bayed hangar facilities are placed on pile foundation. The hangar hall including the wings consists of five main steel girders without intermediate columns. Triangular main girders are connected with a purlin and bracing system. The back frame is additionally braced against a new service building. The wings are an integral part of the structural concept, contributing to resist horizontal excitations. The hangar roof is aluminum cladded, the facade consists of two types of glass with a concrete band at bottom. A significant earthquake loading and exposition to typhoons determined considerably the design of the facades.

Length: 175 m (free span) + 29 m (wings)
Width: 97 m (hall) + 24 m (service building)
Height: 41 m
