Learning outcomes of the course unit

Students get the basic knowledge of structural mechanics needed for the further study of civil engineering branch and of the following specializations. The theoretical knowledge and its application ability represent the possible base for later evaluation of loading capacity, security and reliability of structures.
Students will be able to solve reactions and internal forces of the plane statically determinate structures, of plane beams with straight and broken axis, to solve three-hinged broken beam with and without a bar, the planar composed beam systems and plane truss systems, to find centroid and second order moments of cross-section.

Prerequisites

The basic secondary s school knowledge from mathematics and physics.

Co-requisites

Linear algebra, foundations of matrix calculus, solving of linear algebraic equations systems, foundations of vector calculus, analytical geometry, first derivative of function, indefinite integral, definite integral.

Planned learning activities and teaching methods

The subject is taught by lectures and exercises. Lectures involve the theoretical explanation of delivered matter. The theory is applied at solution of examples of real structures in exercises.
Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

The subject is finished by abridged examination and final examination. For abridged exam the student should pass all written tests in exercises and elaborate correctly all given homework. The abridged exam is the necessary condition for final examination entrance.
The final examination consists of written and oral parts. The written examination may contain both examples and the theoretical questions. The positive result in written examination allows the student to pass to oral part.
