Objectives
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.
Prerequisites
It is assumed that the students have acquired the concepts taught in Strength of Materials I and II.

Teaching method
Reinforced Concrete Structures II has two lectures classes each week with 1:30h each, and one problem solving session with a duration of 2h.
In the lectures classes the subjects are presented and in the problem solving sessions 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 problem solving sessions.
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(P) and Lectures Ac(T)
Ac(P) = 0 to 20.
Ac(T) = 0% to 100%.
Ac = Ac(P) x Ac(T) ≥ 7.5
4. Final Grade = 0.8 x NE + 0.2 x Ac
Students with a final grade greater than 16 must do an oral exam.
