The textbook outlines the basics of the theory with detailed methodological examples of calculations from the following main sections of the course of structural mechanics: calculation of statically definable and statically indeterminate rod systems; beams on elastic base; stability and dynamics of rod systems; bending and torsion of thin-walled rods of open profile; calculation of cylindrical shells and thick-walled pipes; fundamentals of plasticity and creep theory; limit equilibrium state of systems; reliability of structures.
