1. The Akashi Kaiko Bridge By Mr. Kaufman
Bodine High School For International Affairs
2. The Akashi Kaiko Bridge This is the longest suspension bridge in the world.
Above the Akashi Strait between Maiko, Tarumi-ward in Kobe, and Matsuho, on Awaji Island.
3. It has 6 lanes and can support cars going 100 km/hr.
The bridge has a total length of 12,832 feet (2.43 miles).
It was only slightly damaged in The Great Hanshin Earthquake of 1995 which destroyed much of Kobe. It was built to stand a 8.5 Richter-scale quake.
4. The bridge is a 3-span 2-hinged truss-stiffened suspension bridge.
5. 90,000 tons of steel were used in constructing the stiffening girders so it can withstand the strong winds in the strait (which can gust up to 179 mph).
7. To reduce stiffening girder torsional vibration caused by wind, stabilizing plates were installed under the median strip of the deck. The stabilizers act to guide the wind, reducing torsional vibration by achieving a balance between pressures on the bridge lower and upper surfaces.
9. each suspension cable is made of 36,830 wires of steel
