2. Objectives and learning outcomes
2.1 Objectives
The aim of the subject is to discuss the behaviour of thin-walled members, particularly that of cold-formed steel members. Special emphasis is given to stability behaviour, as well as to state-of-the-art numerical methods that can beneficially used in stability analysis.
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
  1. knows the most important specialties of cold-formed steel members,
  2. knows the characterizing behaviour types of cold-formed steel members,
  3. knows the characteristics of the typical buckling types of thin-walled members,
  4. knows the special numerical methods that can beneficially applied in the stability analysis of thin-walled members, and understands the basic concepts of these methods,
  5. understands the design approaches for stability of cold-formed steel members,
  6. understands the basics of Eurocode design for cold-formed steel members.
B. Skills
  1. is able to use special numerical methods for the stability analysis of thin-walled members,
  2. is able to perform design calculations for cold-formed steel members,
  3. is able to individually research a topic related to thin-walled members, by collecting and evaluating relevant background literature,
  4. is able to prepare a summary/presentation on a topic related to thin-walled members.
C. Attitudes
  1. openness to elaborate new problems,
  2. awareness of the importance of knowing the mechanical/mathematical background of numerical/design procedures/tools,
  3. awareness of the importance of seemingly small (mechanical/mathematical) details when approaching a practical problem.
D. Autonomy and Responsibility
  1. completing literature review individually,
  2. elaboration a topic individually,
  3. preparation a scientific presentation individually.
2.3 Methods
Lectures, and individual work: preparation of a summary/presentation on a selected topic.
