Record spans in Japan
Article Abstract:
Japan is conducting an ambitious 30-year project aimed at connecting two of its major islands, Honshu and Shikoku. Managed by the Honshu-Shikoku Bridge Authority, the initiative will involve the construction of 18 bridges that would form three different highway routes. The project includes 10 suspension and six cable-stayed bridges, an arch, a truss bridge and connected roadways. The most impressive components of the system are the Akashi-Kaikyo and Tatara bridges, which are touted as the longest suspension and cable-stayed bridges in the world.

Japan shows the way with aramids
Article Abstract:
Japanese researchers have developed prestressed concrete tendons using plastic rods reinforced with aramid fibers. Tests show that the tendons possess high durability and chemical resistance, stable tensile strength, corrosion resistance, light weight and low elastic moduli. Aramid tendons are especially useful as brackets for anchoring external cables found in concrete bridges since the tensile rigidity of aramid fibers allows it to undergo minimal stress change from displacement.

New construction materials proliferate in Japan
Article Abstract:
Japan is searching for new construction materials and methods of construction to reduce the need for manpower, human error and to improve the condition of the workplace. These new methods and materials should reduce currently higher construction costs in Japan as compared to the US. New improved materials already obtained include advanced concretes and fiber-reinforced composites. The leading construction firms of Japan are investing in the research.
