Institute of Structural Mechanics (STM)

Entry knowledge

Basic knowledge of mathematics and physics from secondary school is required.

Rules for evaluation and completion of the course

The course is finished by credit and final examination. The credit is a necessary condition for final examination entrance. To gain credit, the students should pass two control tests during the semester. The active presence in practical classes is checked. The exam consists of written and oral parts, in which the practical examples and the theoretical part are elaborated. To pass the exam successfully, all parts should be accomplished.

 

The definition of monitored instruction and the method of its implementation is annually updated by the guarantor of the course

Aims

Students will be acquainted with reactions and internal forces of statically determinate plane beams and frames, and geometric properties of cross-sections (centroid, second moments of area). They also will be acquainted with basic concepts and assumptions of the linear elasticity and strength theory, such as stress, displacement, and deformations and look into the dimensioning of structures.

Students will be able to solve reactions and internal forces of statically determinate plane beams and frames, determine centroid and second moments of area, solve simple and combined bending and direct stresses and calculate stress in cross-section to design its dimension and material.
