Associate Professor, Dept. of Civil and Environmental Engineering

“I study bridges. I teach steel structure and design methods of bridges, in order for our students to be able to design simple plate girder bridges. I have done studies of the efficient construction and maintenance of real bridges.

Recently, I developed a support system for cable tensioning of cable-stayed bridges in cooperative research with a cable manufacturing company. Each strand is tensed using the PC-controlled hydraulic jack while watching the monitor. To achieve safe and efficient operation, the computer calculates, in real time, optimum manipulated variables for hydraulic jacking from the strand tension data and measurement data of the bridge.”
