Course description and aims

In this course, in order to understand the safety management of steel structures, students will obtain the knowledge on the causes of fracture phenomenon in steel structures and on the approach of fracture mechanics necessary for the prevention of occurrence of fractures and countermeasures against them. In addition, students will obtain a deeper understanding on the causes of fracture damage cases, countermeasures and their effectiveness against them, by conduction group discussions and presentations.
This class is aiming to provide necessary technical knowledge for the safety management of infrastructures, and to enhance students' ability of communication and their ability to solve problems.

Student learning outcomes

By the end of this course, students will:
1) Be able to explain about the fracture types in steel structures such as brittle fracture or fatigue fracture.
2) Be able to explain about the causes of fracture phenomenon in steel structures and the countermeasures against them.
3) Be able to explain about the approach for fracture control from fracture mechanics.
4) Be able to explain about fatigue design methods of steel structures.
