Learning unit contents
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.
French-Englidh Dictionnary

Learning outcomes of the learning unit
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.
Prerequisite knowledge and skills
Good understanding of structural mechanics and stability of constructions.
Planned learning activities and teaching methods
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 of delivery (face-to-face ; distance-learning)
The course is given face to face
Recommended or required readings
There exist a syllabus containing the lecture notes, updated every year. It iwill be available in electronic format on "MyUlg".
Assessment methods and criteria
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.

Organizational remarks
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.
