### CIV-E4100 - Stability of Structures D, Lecture, 26.2.2024-18.4.2024

Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.

#### LEARNING OUTCOMES

A Student

-  understand the basic concept of Stability and its nature, Equilibrium paths, stable, unstable.
