Fatigue (3 ECTS)
The student will learn how to design fatigue loaded steel, aluminium, concrete and timber structures. Two-thirds of the course is spent on lectures, while the remaining part is dedicated to exercises. The main topics are:
- Fatigue actions: basic principles; determination of stresses and stress intensity factors; stress history.
- Fatigue resistance: basic principles; classified structural details; fatigue strength modifications; resistance against crack propagation; resistance of joints with weld imperfections.
- Fatigue assessment: general principles; S-N curves; crack propagation calculation; service testing; parameters influencing the fatigue strength of steel, aluminium, concrete and timber connections and structures; safety considerations and synthetic fatigue curves.
