Course title
Maintenance of Steel Structures

Course description
Many types of deterioration in steel structures have been reported and maintenance works is currently urgent issue in Japan. Since the numerous number of deterioration cases have been reported, not only continuous maintenance works but also the developments of effective inspection and repair methods are needed. In this course, professor first gives the information about deterioration cases in steel bridge structures and their mechanism. Then, information of inspection and repair methods including newly developed technology will be given to the students.
Purpose of class
The purpose of this class to understand the current situation of infrastructures in Japan, especially steel bridge structures. Then, students understand how to solve these detrioration problems in the design and maintenance stages through the classes about design and maintenance skills and actual maintence works.
Goals and objectives
  1. Students understand current health conditions of infrastructures in Japan, especially steel bridge structures.
  2. Students understand the mechanism of fatigue and corrosion in steel bridge structures
  3. Students get knowledges about inspection and maintenance methods
