Message
Many of the steel structures in Japan rapidly increase more than 50 years after the construction, maintenance of these steel structures will become increasingly important. We are aiming at research on structural analysis technology and corrosion environment evaluation for rational inspection and diagnosis of steel structures that have passed through many years.
