The basics of Mechanics of Materials are assumed to be well known.
The course is intended to be assessed after a positive grade (equal to or higher of 18/30) in the oral examination, which mainly covers the part related to reinforced concrete structures. In order to access the oral examination, the students need to positively sustain a written examination inherent the solution of plane frame structures subjected to static loads and restraint settlements with the stiffness method, and the solution of a beam with the flexibility method. A positive judgement from letter A to letter C, being A the maximum, will be attributed to the written exam. This judgement will have orientative influence on the oral examination result.
It is also necessary to deliver at the oral examination the following homework developed independently by the student:
- serviceability and ultimate limit state checks of a reinforced concrete structural element.
In case of refusal of the final score, the student should communicate it within 5 days after the publication of the vote in the ESSE3 platform.
AIM OF THE COURSE
The aim of the course is to provide the students with the following skills: (a) resolution of statically determined and undetermined beams, (b) resolution of planar frames with the stiffness method, (c) notions on the semiprobabilistic method of limit states, (d) load analysis, (e) design techniques of reinforced concrete structures in service, (f) design techniques of reinforced concrete structures at failure, (g) structural detailing of reinforced concrete elements.
LEARNING OUCOMES
