BūvZ4108, Reinforced Concrete and Masonry Structures I

In this course students will gain knowledge about the structural design of reinforced concrete and masonry structures and will obtain skills to evaluate the safety and serviceability of the structures.

In the course the basic design and detailing aspects of prefabricated and pre-stressed concrete structures are covered.

1. Students will gain knowledge about the basics of limit state design and structural analysis in case of reinforced concrete structures – test 1 to 3, final test, and examination.

2. Students will gain knowledge about the types of reinforced concrete and masonry structures, the design methods, and rules for detailing and drawings – test 4 to 8, final test, and examination.

3. Students will have conception of the basic design principles and detailing rules for prefabricated and pre-stressed concrete structures – final test.

4. Students will have skills to do the limit state analysis for reinforced concrete structures and its components – practical work (problems) 1 to 10, examination.

1. Lecture: Introduction. Design of reinforced concrete structures – overview. (2h)

2. Lateral stability or concrete buildings; design principles for shear walls. (2h)

3. Limit state design, Design situations and Load combinations. Structural analysis in concrete structures. (2h)

4. Concrete ceiling slabs: types and design principles. (2h)

5. Beams: types and design principles. (2h)

6. Design of short and slender columns. Prefabricated columns. Biaxial bending. (2h)

7. Concrete foundations: types and design principles. Design of pile caps. (2h)

8. Rules for detailing of concrete structures. Laps and anchorage of reinforcement. (2h)

9. Drawings of reinforced concrete structures. (2h)

10. Masonry structures. Material properties. (2h)

11. Failure modes of masonry structures. Design of unreinforced masonry walls under compression. (2h)

12. Design of unreinforced and reinforced masonry structures under tension and bending. (2h)

13. Prefabricated concrete structures. (2h)

14. Pre-stressed concrete structures: basic principles and requirements for materials. (2h)

15. Design of pre-stressed concrete structures according to the limit state method. (2h)

16. Losses of stresses in pre-stressed concrete structures. (2h)

The evaluation process of students will take place during the whole semester that will end with the final test and the examination. The following order in the evaluation process is compulsory:

1. First the tests and practical works (design problems) must be completed; lectures must be attended (80% or more); course project must be completed and defended (BūvZ4109).

2. Then students are allowed to take the final test.

3. After the final test is passed, students are permitted for examination.

The course is passed when the examination is passed successfully.

Practical works. The design problems are available only in a particular computer room of the Faculty of Environment and Civil Engineering. They must be completed independently and submitted in e-learning course page.

Tests must be completed independently and submitted in e-learning course page. They are available also outside the University building.

Independent works. There is no independent work required for students in this course. Nevertheless students can do an Independent work to compensate the lacking attendance. In this case one must prepare a learning aid for the next year students. The work can be done independently or in groups. Options for the work: created or improved a wiki page in the e-learning course site; virtual detailed 3D models for reinforced concrete structures; small scale physical models for concrete structures; specimens for advanced laboratory testing, etc. The independent work must be first confirmed by the responsible university lecturer.

The examination consists of a comprehensive design problem. Any printed source may be used. Students must solve the problem and defend it orally. Additional questions from the whole course material, especially those related to the particular problem, can be asked. The grade depends on the calculations and the level of knowledge presented during the examination. A student fails the examination, if a serious mistake in the calculations is made (if the mistake would lead to a possible failure of the designed structure), and/or if he/she is not able to explain the meaning of the calculations performed by him/her.

In the final test the minimum necessary knowledge will be evaluated (it is around 50% of the whole learning material), therefore the score must be 80% or more of the maximum possible. The test can be retaken until it is passed, but not more than once a week.

The attendance of the lectures must be 80% or more. If a student is late for an activity or his/her absence is justified, 50% of attendance is assigned. If the total attendance of a student is less than 80% of the maximum possible, an independent work will be assigned.
