Prerequisite or corequisite units are presented within each program

Learning unit contents

General considerations about structures and their history, reflexions about natural phenomenon. Discussions about existing structures. General approach to solve a problem of Strength of materials. Mechanical properties of materials. Actions on structures. Force and moment. Equilibrium. Modelization of supports. Internal forces M, N, V and T. Degree of redundancy. Calculation of trusses. Internal forces and force diagrams. Geometrical characteristics of the sections. Stresses in the elements subjected to normal force (N), bending (M), biaxial bending (Mx, My) and composed bending (N, Mx, My). Design of the elements of structures. Shear stresses due to shear and torsion forces. The circle of Mohr. Laws of behaviour for different materials. Deformations and displacements. Buckling. Optional complements : calculation of hyperstatic structures and of cables.

Learning outcomes of the learning unit

The course describes the basics of the strength of materials and elasticity. The course is a preliminary to other specific courses of the STE orientation as Constructions Processes and Stability of the Constructions.
After completing the course the student is expected to :
- Easily deal with the basic aspects of the Mechanics of Structures and the Strength of Materials (all materials) - Understand the spread of forces, stresses and displacements inside structures - Design and calculate elementary structures

Prerequisite knowledge and skills

Mathématique générale, first Part
Mathématique générale, second Part
Physique générale

Planned learning activities and teaching methods

All the forecast hours are hold by the professor himself in auditorium. Generally, each course takes place as following:
- Short remind of the previous courses - Exercises solved and commented on the blackboard by the professor and discussed with the students - 10 minutes break - Continuation of the theory with the help of a Powerpoint slide show

Mode of delivery (face-to-face ; distance-learning)

Lectures : 18h Practical Works : 18h

Recommended or required readings

1. Course notes (150 pages x 2 slides) 2. "Introduction à l'analyse des structures", M.A. Studer et F. Frey, Presses Polytechniques et Universitaires Romandes, 368 pages, 1999. 3. ISSD : Interactive Software for Structural Design (www.issd.be). Availlable in the computer training rooms of the Faculty.

Assessment methods and criteria

Written examination which includes a part of theory with books closed and a part of exercises with books opened. A note of 10/20 requires to pass both parts. The exam lasts from 2 to 4 hours, according to the cases. A first elementary question is given during the exam : if not passed, the rest of the exam will not be corrected and the final note will be 0/20.
