Aims
 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

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.

Teaching methods
Ex-cathedra teaching with the help of slides for the volume 1. Practical works with the assistants for the volume 2
Evaluation methods

Exam of about an hour, about the theoretical concepts of the course (PART I) + exam of about 3 hours with practical problems to solve (PART II). The theoretical exam may include a demonstration. For the PART II exam, students can only have a personal handwritten summary on a single, double-sided A4 sheet.
The success of both parties is required. If one of the two parties is in failure, the resulting score will be the minimum between the average score and 9/20.
An eliminatory question on very basic aspects of the course is provided at the beginning of the exam. The final score will be 0/20 if this eliminatory question is not successful
Other information
A didactic software for calculating structures (see www.issd.be) is used during the course and TPs and is made available to students in computer room. Its use is highly recommended
