Supervisor

Professor / IWASAKI Eiji , Associate Professor / MIYASHITA Takeshi
Mr. Iwasaki is involved in redundancy assessment of steel structures, load carrying capacity of existing structures, and deterioration of steel structures by corrosion.
Mr. Miyashita is engaged in structural health monitoring. And he develop new technologies for the construction of bridges with Ministry of Land, Infrastructure, Transport and Tourism.

Research Content

In our laboratory, we have conducted research on steel bridges. Steel bridges have various types of structures and have different characteristics and properties. Our research activities include analysis of the behaviors that occur due to those difference, finite element analysis using DIANA, investigation of bridge corrosion using weathering steel, investigation of the effects of CFRP (Carbon Fiber Reinforced Plastics) on bridge repair and reinforcement, and structural health monitoring for bridge maintenance and management. We will continue to conduct research on the following topics.

CFRP construction

A Day in the Lab

In the steel structure laboratory, we don't have core hours, and we carry out structural analysis and experiments based on our own research themes. However, it does not mean that we do research all day long, but we sometimes chat so there is a loose side to us. In addition, many members like to enjoy events such as inter-laboratory games and Nagaoka fireworks, and we are a congenial laboratory where people are willing to enjoy university life while doing research. Another feature is that many international students are enrolled in our laboratory, and we can train our English skills while experiencing various cultures of the world.
