Course abstract

The objective of the study course is to give knowledge about physical and mechanical properties of steel and aluminium alloys. Design principles of metal structures according to limit state method including strength, stability and stiffness conditions for structural elements and connections are acquired. Design of beams, axially loaded columns and trusses are discussed.

Learning outcomes and their assessment

Student is able to use the material’s mechanical characteristics and their dimensions in calculations, and to check capacity of structural element loaded in tension, compression, bending.
Learning assessment is examination.

Requirements for awarding credit points

Successfully settled examination within which test is settled and homework defended.

Description of the organization and tasks of students’ independent work

Individual home work must be developed which helps to prepare for test and examination. After test is completed student has a permission to participate in examination.

Criteria for Evaluating Learning Outcomes

Student will have positive assessment in examination where three correct answers out of four must be answered, after test is successfully settled and individual homework defended.
The home work will be assessed basing on two criteria:
1) correctness of results;
2) ability to participate in conversation on calculations and results.
