Linear algebra, fundamentals of matrix calculus, solutions of systems of linear algebraic equations, vector calculus, analytic geometry, derivative of a function, indefinite and definite integral, applications of the integral. Determination of reactions and internal forces of statically determinate plane beams and frames.

Co-requisites

Planned learning activities and teaching methods

Methods of teaching depend on the type of course unit as specified in article 7 of the Study and Examination Rules of BUT. Education runs in the form of lectures and practical classes. The character of the lectures is based on the explanation of basic principles, problems and methodology. In the practical classes, selected main topics are practised using examples.

Assesment methods and criteria linked to learning outcomes

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. A written exam consists of the part, in which the example is elaborated, and the theoretical part. To pass the exam successfully, both parts should be accomplished.

Aims

Students will be acquainted with influence lines for statically determinate structures. Principle of virtual work and its application to calculation of deflections and rotations of statically determinate beams (unit dummy force method) will be clarified. Students will learn how to solve statically indeterminate beam structures by force method and direct stiffness method. The solution of statically indeterminate structures will be performed on two-sided fixed beam, continuous beam, planar frame, and truss girder. The force load, the effect of temperature changes and the support settlement are considered.

Specification of controlled education, way of implementation and compensation for absences

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