The basics of Mechanics of Materials are assumed to be well known. The course of Scienza delle Costruzioni (Mechanics of Materials) is propedeutical to this course.
The final assessment comprises on written and one oral examination. In order to access the oral examination, the students need to positively sustain a written examination with two exercises: solution of plane frame structures subjected to static loads and restraint settlements with the stiffness method, and solution of a beam with the Mohr corollary or 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 with a possible modification of the mark from the oral exam of 2/30.
The course is intended to be assessed after a positive grade (equal to or higher of 18/30) in the oral examination, which covers all the subjects of the course. The main contributions to the final mark, in addition to the knowledge of the content, are: capacity to orally expose the knowledge; capacity to critically analyse and extrapolate from the knowledge; quality of the speech and skill in the use of the technical dictionary. To facilitate the preparation of the exam, a list of recurrent questions will be available to the students.
It is also necessary to present during the oral examination a homework developed independently by the student concerning the non-linear behaviour of a statically-determined reinforced concrete structural element.
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 structural design: semiprobabilistic method of limit states and load analysis, (d) design techniques of reinforced concrete structures in service, (e) design techniques of reinforced concrete structures at failure, (f) structural detailing of reinforced concrete elements.

The course is based on frontal theoretical lectures, included the development of applicative examples. The students will also autonomously solve practical problems with individual homeworks. Technical visits, to be confirmed, are scheduled with non-compulsory attendance in hour slots other than the official ones of the course.
Students can meet with the professor in his office by previous phone or email appointment.
