Contenus de l'unité d'enseignement

This course is dedicated to the utilisation of wood as a material for structures in buildings. Because of its light weight, its good environmental perception and, under some conditions, the good fire resistance that it allows to achieve, wood is more and more utilised for the construction of housses and for the roof of commercial and industrial buildings.
The course is divided in 7 chapters and 2 annexes: 1. Introduction Comparison between the situation of the timber construction in Belgium and in other parts of the world. Reasons of the main differences; cultural reasons, fear linked to fire and doubts about durability. Advantages of the timber construction. 2. Properties The tree. Constitution of timber. Main properties of timber: relative humidity, shrinkage, thermal expansion, specific mass, compressive strength, tensile strength, bending strength, shear strength, chocs, coefficients of elasticity, stress-strain diagram. 3. Utilisation of timber in construction Circular sections. Square sections. Glue laminated timber. Different families of panels. 4. Design General principles and formulae dor the verification of elements under different effects of actions. 5. Connections Introduction. Traditional connections. Dowel type connections. Other mecanical connections. General considerations. Some examples of common connections. 6. Durability Protection against fire. Protection against roting: choice of the species, constructive protection, chemical protection. Attacks by insects 7. Structures Introduction. Beam in bending. Arches. Frames. Trusses. Houses.

Acquis d'apprentissage (objectifs d'apprentissage) de l'unité d'enseignement

At the end of this course, the student will be able to take into account the particularities and the properties of wood to make the conceptual design of a timber structure. He will be able to design the elements of a timber structure. He will be able to take constructional protection measures in order to garantee a good durability to the timber construction that he will create. He will be able to select the most suitable connection type and to design it.
The complete list of KLO's/AA for this course is defined in the matrix that can be found at: https://www.programmes.uliege.be/cocoon/20182019/formations/descr/A2UCON01.html

Savoirs et compétences prérequis

Good understanding of structural mechanics and stability of constructions.

Activités d'apprentissage prévues et méthodes d'enseignement

The "theoretical" considerations are presented during the course by the teacher.
As an application, the students will then project and design (either individually or in a group of 2 students) a small structure under supervision of the teacher and assistant.

Mode d'enseignement (présentiel, à distance, hybride)

Cours donné exclusivement en présentiel


Explications complémentaires:

The course is given face to face, depending on the evolution of the COVID situation.

Lectures recommandées ou obligatoires et notes de cours

There exist a syllabus containing the lecture notes, updated every year. It is available in electronic format on "MyUiege".

Modalités d'évaluation et critères

Examen(s) en session

Toutes sessions confondues

- En présentiel

évaluation orale

Travail à rendre - rapport


Explications complémentaires:

60% of the points are awarded for a project that the students have to do, partly during the time of the course, partly outside the hours of the course. 40% of the points are awarded for the oral examination. For this examination, a list of questions is distributed to the students when the course is finished. On the day of the examination, each student draws at random two questions among the list. He will then discuss the subject with the teacher after having prepared his answer on a blackboard. The lecture notes cannot be used during the examination.

Stage(s)

Remarques organisationnelles et modifications principales apportées au cours
