Aesthetic Design of Haneda Sky Arch

Abstract

The Haneda Sky Arch, located in front of the new passenger terminal of Tokyo International Airport (Haneda Airport), consists of a pair of steel-cable-stayed girder superstructures supported by a main arch pylon. In the construction of the new terminal, two design concepts were given priority, recognizability and architectural harmony. To help achieve such a goal, this unique arch bridge was designed to become the symbol for the newly enlarged airport. The three-dimensional arrangement of the cables lends an elegant grace to the Sky Arch when viewed from various vantage points, and its unique structural form makes it readily identifiable. The Sky Arch integrates numerous interesting features, including (a) slender main girder superstructures that suggest the lines of an airplane's wing, (b) interesting stainless steel details, (c) smooth cold-worked curves on arch rib corners, and (d) field-welded splices to minimize the use of mechanical fasteners. These features are in complete harmony with the architecture of the other facilities. Fulfilling both functional and decorative purposes, the remarkable design of the Haneda Sky Arch enhances the overall attractiveness of the new airport facilities.
