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

Each week this course has two lectures classes, with 1h30m each, and one problem-solving session, with 2h.

Laboratory test of a reinforced concrete beam subjected to bending.

 

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.
