Course description and aims

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.

Student learning outcomes

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

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

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.

Out-of-Class Study Time (Preparation and Review)

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.

Reference books, course materials, etc.

Course materials are provided during class.

Assessment criteria and methods

Students will be assessed on their understanding of instability, and their ability to apply them to solve problems.
