This course focuses on instability of steel structural members and frames. This is very important issue for designing steel structure. In each class, structural member stabilities and specification for steel structure in Japan, USA and Europe are introduced.
Students will learn the advanced design methods for solving the instability problems of steel structure, and recent new topics about steel structure given by a guest speaker.
At the end of this course, students will be able to :
1) Explain instability of steel structure and the concept any specification.
2) Develop the ability to solve instability issue and design steel structure.
3) Compile a report based on the findings.
Structural Engineering, Steel Structure, Stability
|✔ Specialist skills||Intercultural skills||Communication skills||✔ Critical thinking skills||✔ Practical and/or problem-solving skills|
In each class, structural member stabilities are explained. New topics about steel structure are shown from a guest speaker. In the last class, group work exercise will be conducted to assess the students’ level of understanding on what has been taught so far.

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
No textbook is set.
Course materials are provided during class.
Students will be assessed on their understanding of instability, and their ability to apply them to solve problems.
