Enabling students for design, application of principles and methods for calculating and dimensioning prestressed elements, as well as for the analysis on the condition of usability of reinforced concrete and prestressed elements.

Knowledge and application of principles and methods for calculating and dimensioning prestressed elements, as well as the analysis on conditions of usability of reinforced concrete and prestressed elements. Necessary fundamentals for other professional courses in the field of concrete structures.

Limit states of reinforced and prestressed concrete elements: the calculation of sectional stress-strain distribution, calculation of deflections/deformations and cracks. Limit deflections and crack widths. The design criteria. Review and development of prestressed concrete elements and technical regulations. Prestressing models (pre and post tensioning). Principles, systems and levels of prestressing. Properties of the concrete (concrete creep and shrinkage) and reinforcement (strength, stress relaxation). Working relationships of concrete and steel for prestressing. Concrete creep theory and algebraic stress-strain relationship. Design of prestressed sections and the allowable stresses of ultimate bearing capacity. Short- and long-term time losses of the prestressing force. Cable route, cable anchoring, the length of the introduction of the force and ensuring the elements by reinforcement. Limit state of crack initiation. The application of the PN within linear and shell elements.

Lectures, exercises, consultations, preparation and defense of the project.
