Learning outcomes

Student will learn and master basic principles a methods of design of the load bearing members of metal structures. Further they will learn and manage the design techniques and procedures of the actual load bearing members and parts according to the standardized European documents.
Partial problems include the questions of material characteristics, dimensioning of connections, design of members under tension, bending, torsion and compression. The essential design problem of the slender and thin-walled members are the tasks focused to the stability and buckling strength of the compression members and beams.
In general, the subject content will be focused to the questions of reliability and efficiency of the load bearing structures.

Prerequisites

Basics of university mathematics, physics and chemistry, statics, strength and plasticity, section characteristics, design principles of structures and traffic constructions, loading of structural systems.
