Wooden structures
Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

Aims

At the end of this learning unit, the student is able to :

1 AA1.1, AA1.2, AA1.3, AA2.1, AA2.2, AA2.3, AA2.4
At the end of this course, the students must be able to:
  • Choose the timber material knowingly, according to its advantages, disadvantages, and specificities of structural design;
  • Design the structural elements subjected to all the combinations of loads (N, M, V, T) by applying the rules of the EC5;
  • Design and calculate simple carrier systems;
  • Design and calculate simple connections;
  • Integrate the fire problem in the design

Teaching methods
Lectures for the volume 1. Tutotials for the volume 2.
Evaluation methods
Exam of about an hour, about the theoretical concepts of the course (PART I) + exam of about 3 hours with practical problems to solve (PART II). For the PART II exam, students can only have a personal handwritten summary on a single, double-sided A4 sheet.
The success of both parties is required. If one of the two parties is in failure, the resulting score will be the minimum between the average score and 9/20.
An eliminatory question on very basic aspects of the course can be provided at the beginning of the exam. The final score will be 0/20 if this eliminatory question is not successful.
