Course detail
Limit States of Structures I
FSI-RMK Acad. year: 2027/2028 Winter semester
Active participation in seminars and elaboration of assigned semester projects is required for granting the credit. The exam consists of a written part in the form of test questions and, if necessary, an oral part.
Participation in the exercises is mandatory. Non-participation can be compensated for by completing the exercise assignment and demonstrating knowledge of the topic covered. Longer absences are compensated for by a special assignment according to the instructions of the instructor or lecturer.

Entry knowledge
Static structural analysis of beam bodies.
Empirical calculation of machine parts.
Static structural analysis of parts using finite element method.
Material characteristics of metallic materials (without a crack and with crack) in terms of monotonic and cyclic loading and also in terms of reduced, normal, and elevated temperature.

Aims
The objective of the course is to make students familiar with the concepts and characteristics of limit states. From the extensive set of limit states, increased attention will be paid only to the most common limit states, i.e. limit states of fatigue and brittle failure with respect to current methods, standards, and regulations.
Gaining an overview of the limit states during the design and assessment of metal structures. In further technical practice, graduates will be able to specify the individual steps of assessment according to the necessary regulations, standards or guidelines.
