Contenus de l'unité d'enseignement

This course is dedicated to the utilisation of wood as a material for structures in buildings, bridges and footbridges. 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 footbridges, 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. 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 create 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. Il will be able to select the most suitable connection type and to design it.

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 a small structure under supervision of the teacher and assistant.

Mode d'enseignement (présentiel ; enseignement à distance)

The course is given face to face

Lectures recommandées ou obligatoires et notes de cours

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

Modalités d'évaluation et critères

1/2 of the points are awarded for the project. 1/2 of the points are awarded for the oral examination. For this examination, a list of subjects is distributed to the students when the course is finished. On the day of the examination, each student draws at random two subjects among the list. He will then discuss the subject with the teacher after having prepared his answer on a blackboard. The lecture notes can not be used during the examination.

Remarques organisationnelles

In 2017-2018, the course will be given during the first quadrimester, on Wednesday, from 1:30 PM to 5:30 PM. The course will be given in English.
