Course contents :
|
| This course is dedicated to the utilisation of wood as a material for structures in buildings, bridge and footbridges. Becasue of its light weight, its goos 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.
Dictionnary

Learning outcomes of the course :
|
| 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. |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| 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.
Some simple practical exercices are made together by the teacher and the students during the course. As an application, the students will then, in groups of two students, realise a small first project under supervising of the teacher. |
|
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 is distributed the students in electronic format. |
|
Assessment methods and criteria :
|
| 1/3 of the points are awarded for the small project.
2/3 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 explain the answer to the teacher after having prepared the answer on a blackboard. The lecture notes can not be used during the examination. |

|
Organizational remarks :
|
| In 2013-2014, the course will be given during the second quadrimester, on Friday, from 1:30 PM to 5:30 PM.
The students who have particularly appreciated the topic of the course and want to push it further can choose, or even propose, the next year a subject in the domain for their graduation work. |
