Acquaints the students with the theoretical foundations of structural mechanics, the understanding of which leads to the knowledge of static action of and strain in the supporting elements of building structures. For an architect, the knowledge of the fundamental laws of structural mechanics is indispensable, since it is the modern logic basis of the most important stage of his work, i.e. the formulation of the concept. The subject is conceived in the spirit of the common principles of structural analysis, completed with examples of practical application.

1. Tasks of structural mechanics, basic conceptions, presumptions. Plane systems of forces. Equilibrium and equivalence.
2. Basic types of statically determinate beams. Calculation model of planar beam, load actions, supports.
