Learning outcomes

At the end of this learning unit, the student is able to :
1	At the end of the course, the student will be able to Understand and apply the principles of the distribution of forces, constraints and deformations within the structures; Design and calculate isostatic structures composed of compressed or tensioned bars, bent beams, cables, funicular arcs, elements subjected to combined forces; Choose the types of structural elements and building materials by measuring the consequences of his choices on the behavior of structures. The course helps to develop the program's AA: A1.1, AA1.2, AA1.3

Teaching methods

Ex-cathedra and/or podcasts based on slides for volume 1. Supervised practical work in the classroom or remotely for volume 2.

Evaluation methods

The exam is closed book and will consist of an approximately one-hour theoretical portion on structural mechanics and an approximately two-hour exercise portion with practical problems to solve. The theory part may include a demonstration. For the exercise part, the students can only have a handwritten personal summary on one A4 sheet, double-sided. Failure in either part will result in a final grade of less than 10/20 (both parts must be passed).
The evaluation will cover all parts of the course. The chapters related to the calculation of internal forces and the drawing of internal force diagrams will have to be perfectly mastered. In addition, a good overall knowledge of the theoretical aspects of the course is necessary for success.

Other information

A didactic software for structural calculation (see www.issd.be) is used during the course and the practical work and is available to the students in the computer room. Its use is highly recommended.
