Reinforced Concrete Structures I


This course has the purpose of providing basic information on reinforced concrete structures, focusing namely on the durability of reinforced concrete and on the design approach adopted in the Eurocodes, based on the verification of safety to limit states.In the course, the analysis of structural elements (e.g. ties, beams and columns) is presented using the concept of ultimate and serviceability limit states. Detailing of such elements is also addressed.

Attention is also given to the design and detailing of reinforced concrete structures under seismic and fire actions.

Teaching method

Reinforced Concrete Structures I has two lectures classes each week with 2:30h each.

In the lectures classes the subjects are presented and the students solve practical problems with the guidance of the professor.

The evaluation will be done with basis on a final exam, exercises and the problems solved by the students in the classes.


Evaluation method

The evaluation of knowledge has two components: one done by works and classroom participation of the student during the semester and the other by two minitests or final exam.

1. Minitests

Written minitests  NE = (1stMT + 2ndMT)/2, grade = 0 to 20 (≥ 7.5).

2. Exam

Written exam NE, grade = 0 to 20 (≥ 7.5).

3. Works and classroom participation

Problem solving sessions Ac ≥ 7.5      Ac = 0 to 20.

4. Final Grade = 0.8 x NE + 0.2 x Ac

Students with a final grade greater than 16 must do an oral exam.
