### Course abstract

In this course the basic principles of reinforced concrete structures, materials and section analysis are studied.
Students learn to evaluate the load bearing capacity and to analyse different types of reinforced concrete beam/slab sections. Laboratory test demonstrations are used to illustrate the features of mechanical behaviour of real reinforced concrete beam model under flexural load and to compare the results with the theoretical values calculated before.

### Learning outcomes and their assessment

1. Students gain knowledge about the basics of reinforced concrete structures, material properties, and section analysis of reinforced concrete elements under bending – test.
2. Students will be able to determine necessary longitudinal and transversal reinforcement and to evaluate the section capacity of concrete beams and slabs – design problems (7 problems).
3. Students will be able to manufacture reinforced concrete beam specimens and evaluate the experimental test results – laboratory work.
4. Students will gain the skills to obtain and present the test results, to draw up the test report and make conclusions – laboratory work.

### Course Content(Calendar)

1. Lecture: Introduction. Course overview. Reinforced concrete in building structures; History of development.

11. Lecture: Shear capacity of concrete beams.
12. Laboratory work: Theoretically determined load bearing capacity of the beam specimens.
13. Lecture: Punching shear capacity of slabs.
14. Laboratory work: final remarks on test report, summary of the results and conclusions.
15. Test.
16. Defence of the test report.

### Requirements for awarding credit points

Type of evaluation: a formal test without a grade. To obtain it, the following requirements must be completed:
- attendance of the course activities – 80% of total;
- completed and defended design problems (evaluation of 100% in e-learning course page);
- prepared and defended laboratory test report;
- completed and submitted independent work;
- test passed for minimum required knowledge (80%).

### Description of the organization and tasks of students’ independent work

Practical works. The design problems are available only in the computer class (702) of the Faculty of Environment and Civil Engineering. They must be completed without assistance and submitted in e-learning course page.
Independent works. Students must prepare a learning aid for the next year students. The work can be done individually or in groups. Options for the work: a wiki page created or improved 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.

### Criteria for Evaluating Learning Outcomes

To pass the course, all the requirements regarding the attendance, practical work, laboratory work, independent work, and test must be met.
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, additional independent works will be assigned.
In the test the minimum necessary knowledge will be evaluated, 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.
