Garant předmětu:

Jan Vítek, Lukáš Vráblík

Lecturer:

Jan Vítek, Lukáš Vráblík

Tutor:

Jan Kubát, Jan Vesecký, Jan Vítek, Lukáš Vráblík

Supervisor:

Department of Concrete and Masonry Structures

Synopsis:

Extension of knowledge in the design of prestressed concrete structures. Introduction to special hybrid and thin-walled structures. Modern materials and design solutions for the future.

Requirements:

Knowledge of previous courses in concrete structures and general theory of building structures (structural mechanics, elasticity and strength).

Syllabus of lectures:

13 lectures in total:

1. Basic idea of prestressed concrete, stress distribution in the serviceability limit state (MSP), transition to the ultimate limit state (ILS), prestressing reinforcement path and its influence on beam stresses, materials, MSP design;

2. MSU assessment - principle, partial prestressing;

3. Non-cohesive prestressing reinforcement, statically indeterminate structures, moment addition, calculation, basic relationships;

4. Volumetric changes and their effect on the action of structures, statically certain and indeterminate structures, change in static system, effect on deformation and redistribution of internal forces;

5. Methods of calculation of stress redistribution due to volume changes, force method, relaxation method, numerical methods;

6. Prestressed concrete structures other than bridges, precast elements, prestressed ceilings, tanks, other civil engineering structures;

7. Special cases of prestress management, effects of prestress on plan curved structures;

8. Rope and hybrid structures, structures supported by prestressing cables

9. Slender concrete structures - specifics of the action of slender and very slender concrete structures, principles of calculation, effect of prestressing, buckling length, standard procedures, general numerical methods;

10. Shell structures - basic characteristics, mathematical definition of the centreline area, examples of use, construction methods, structural analysis

11. Shear and torsion - interaction of bending moment and shear force, principal stresses, effects of vertical and transverse prestress, basic theory of torsion, ultimate plastic capacity of section;

12. Basic principles of structural design from UHPC;

13. Summary and review of the material covered;

Syllabus of tutorials:

The exercise involves the design of a prestressed statically indeterminate structure. In the individual weeks of the training, the individual parts of the design and calculation are discussed in turn. The timetable of the exercises corresponds to the time progression of the problem.

Study Objective:

The aim of the course is to build on the existing knowledge in the field of concrete structures acquired during the bachelor studies. Development in the design of prestressed structures. Theory of design of slender and very slender concrete structures.
