Renzo Piano Building Workshop – Architects in association with Nikken Sekkei Ltd Ove Arup & Partners – Structural Engineers

INTRODUCTION
In the late 1960s, the Kansai Region in Japan realized an economic need for a new airport near the Bay of Osaka. Two decades passed before groundwork was laid for Kansai International Airport. To prevent noise pollution and allow for 24-hour a day operation officials chose to build an island in Osaka Bay on which to construct the passenger terminal and runways. 1987-1991: Island construction Simultaneously a design competition was held, for which Renzo Piano Building Workshop (in collaboration with Ove Arup) won the commission. 1991-1994: Airport Construction

INTRODUCTION

Largest man-made island – 22,000,000 cubic meters of reclaimed land, 4 km X 1km in size. Final cost of constructing both island and passenger terminal was $14 billion US dollars. Longest building in the world – 1.7 kilometers Since 1987 the island has subsided approximately 10 meters. Since 2002 the rate of submergence has decreased. Hit by the Kobe Earthquake of 1995 and the terminal sustained no damage.

GEOMETRY

GEOMETRY

The toroid creates a space that is both high in the center portion and low at the ends in order to have unobstructed views of all airplanes and the runway from the control tower.

GEOMETRY
Another roof form generating idea was the desire to condition the passenger terminal without a clutter of ductwork hanging from the exposed trusses. This was done by blowing a jet of air from the landside and let it be carried against a ceiling that would be shaped to follow the natural curve of the decelerating air. Huge scoop like ceilings entrain the blown jets of air across the space.

MAIN TERMINAL BUILDING

MAIN TERMINAL BUILDING

Primary truss type is a Warren based, triangular threedimensional truss Asymmetrically arched tracing the shape of the curvilinear roof above 18 trusses spanning 82.8 meters each Trusses placed 14.4 meters apart

MAIN TERMINAL BUILDING

A continuous secondary structure spans across the primary trusses Built out of standard I-sections with traditional cross bracing Designed to absorb lateral forces generated by earthquakes Also helps restrict potential buckling of the primary trusses

MAIN TERMINAL BUILDING

Gable ends of main terminal are double bow trusses Used to avoid complexity of joining a truss and glazing

WING

Airside The Wing runs the entire 1.7 km span of the structure. This is the side that faces the sea, and therefore receives the blunt of the high force winds during storms. The wing has a separate structural system from the main terminal building. Here, the truss changes to a single tubular steel member supported by tension cables.
