Long-span bridge construction commenced after the end of World War II, when Saikai Bridge, a 243.7 m steel arch bridge in Nagasaki, was completed in 1955.

In an archipelago country such as Japan, long-span bridges are an essential element of transportation links to connect islands and circumvent bays. The availability of advanced steel and reinforced concrete technologies provided an impetus for the construction of longerspan bridges and taller buildings. In the 1900s, the use of reinforced concrete for infrastructure became more common, and pre-stressing technology was widely used for numerous types of simple structural elements in the 1950s. Kiyosu Bridge-an eyebar-chain selfanchored suspension bridge spanning 183 m over the Sumida River in Tokyo-is a representative example of riveted bridges from this era. However, the Great Kanto Earthquake disaster in 1923 revealed the many drawbacks of wrought iron, and high-tensile steels were later adopted for bridges. Starting in 1895, steel quickly replaced wrought iron as the favored material for metal bridges. New bridges built around the 1870s began to be made using cast and/or wrought iron with riveting techniques Kurogane Bridge in Nagasaki (with a span of 27 m) is known as the first modern cast iron bridge in Japan. During this period, people began to use metal as a structural material. This paper also summarizes the lessons learned and feedback obtained from case studies on the structural monitoring of bridges and buildings in Japan.Īfter opening up the country and lifting more than two centuries of rigorous trade restrictions under the Tokugawa Shogunate, modern technologies for the construction of infrastructure were introduced in Japan in 1868 during the Meiji Restoration. Of monitoring systems has been extended to facilitate efficient operation and effective maintenance through the rationalization of risk and asset management using monitoring data.
#AKASHI KAIKYO BRIDGE CONSTRUCTION PROCESS VERIFICATION#
Strategies and case studies on monitoring for the design verification of long-span bridges and tall buildings, the performance of seismic isolation systems in building and bridges, the verification of structural retrofit, the verification of structural control systems (passive, semiactive, and active), structural assessment, and damage detection are described.
#AKASHI KAIKYO BRIDGE CONSTRUCTION PROCESS UPDATE#
In the development of structural monitoring, monitoring systems and collected data were used to verify design assumptions, update specifications, and facilitate the efficacy of vibration control systems.

Structural monitoring systems in Japan historically started with the objective of evaluating structural responses against extreme events. The review focuses on bridge and building structures using vibration-based techniques.

This paper provides a review on the development of structural monitoring in Japan, with an emphasis on the type, strategy, and utilization of monitoring systems.
