Course abstract

The objective of subject is to give knowledge about physical and mechanical properties of steel and aluminium alloys, and design of metal structures according to limit state method. The analysis of strength, stability and stiffness of structural elements and connections is included. Calculation methods and design of beams, centric loaded columns and trusses are given. BIM system software programmes are used - MS Excel, AutoCAD, MathCAD.

Learning outcomes and their assessment

Knowledges about design of steel structures; skills to perform calculation and construction of steel structures; competences to define design problem of steel structure, performe desingn and evaluate the acquired results. Assessment is given on the basis of attendance of lectures, results of tests and individual work.
