Course abstract

The objective of the course is to acquire knowledge about physical and mechanical properties of steel and aluminium alloys, as well as theoretical background for design of metal structures basing on limit state method according to Eurocode 1 and Eurocode 3. The analysis of strength, stability and stiffness of structures and its elements and connections is included. Design of single-storey steel frame of industrial building is mastered taking into account both static loading and dynamic effects. Specific features for design of large span and multi-storey buildings, as well as tall structures as well as thin shell structures are discussed undertaking actual working conditions, design problems and economics of structures. MS Excel, AutoCAD, MathCAD software are used preparing for further work with BIM software.

Learning outcomes and their assessment

Knowledges about design of steel industrial buildings; skills to perform calculation and construction of steel frames and other complicated steel structures according to Eurocodes 1 and 3; competences to define design problem of steel structure, perform design and evaluate the acquired results.
Assessment is given on the basis of attendance of lectures, results of tests and individual course project.
