Learning outcomes of the course unit

Student handle the analysis of linear stability of the frame structures, Euler’s critical force and the shapes of buckled structure. Student will be introduced to the principle of solution of the thin-walled bars with opened cross-section, equation of restrained warping torsion of opened cross-section shape. Student handle the elastic-plastic analysis of a bar, the plastic limit load carrying capacity of a frame structure and the failure limit states. Introduction to solving basic equation of stress analysis and introduction to basics of fracture mechanics with respect to typical structural materials.

Prerequisites

Basic cases and complex cases of the load of the beam, design of the beams in the case of the composed (complex) load, the stability and the bucking strength of the compressed bars, Euler’s solution, the critical force and the critical stress; basics of theory of elasticity – stress, principal stress, deformation, strain, Hooke law, the principal stress at the plane stress problem.

Co-requisites

Force and deformation methods for solving statically indeterminate beams, frames.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Methods of teaching are lectures and exercises. Individual consultations complement teaching. Study activities of students includes entering his own independent work. Attendance at lectures is recommended. Participation in other classes is required and controlled.

Assesment methods and criteria linked to learning outcomes

The subject is completed by credit and final examination. For credit the student should pass all written tests in selected exercises. The credit is the necessary condition for final examination entrance. The final examination consists of written and oral parts. The written examination part includes both examples and theory. The positive result in written examination allows the student to pass to oral part.
