Course description and aims

Learning the basic mechanical characteristics and composition of design formulas of steel structure elements by lectures, and master their basic philosophies by working on exercises. In each unit, the lectures take place in the first half 90 minutes, and the exercises on the same topic as lectures take place in the second half 45 minutes.
Basically lectures are provided on blackboard and distributed appropriate prints. Separately, the structural design challenges of low-rise steel buildings is given which is discussed in the last lecture.
Learning the basic structural design concept and correctly understand the basic mechanical properties of the structural members in the background of design formulas.

Student learning outcomes

I. Learning the basic philosophies of steel structures by lectures, and master the knowledge on the mechanical characteristics and design method through exercises.

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

To enhance effective learning, students are encouraged to spend a certain length of time outside of class on preparation and review (including for assignments), as specified by the Tokyo Institute of Technology Rules on Undergraduate Learning (東京工業大学学修規程) and the Tokyo Institute of Technology Rules on Graduate Learning (東京工業大学大学院学修規程), for each class.
They should do so by referring to textbooks and other course material.
