Contenus de l'unité d'enseignement

The aim of this course is to give students an understanding of the design methods for structures subjected to the fire action. The course is articulated around four key objectives:
(i) Understanding the fundamentals of fire and fire safety. The course covers basics of fire physics, the effects of fire on materials and structures and the multidisciplinary aspects involved in fire safety.
(ii) Evaluating the development of fires in buildings. The course discusses the state-of-the-art methods for prediction of fire scenario, evaluation of fire load and calculation of gas temperatures in a fire compartment. Models of different levels of sophistication are described for fire modelling including nominal temperature curves, analytical localized fire models and advanced computational models.
(iii) Evaluating the fire resistance of structures. The course discusses the state-of-the-art methods for addressing the response of structural elements and entire structures to fire. These include analytical methods, numerical methods (FEM software SAFIR) and experimental methods (fire lab). The course covers the prediction of temperature of the structural elements and the structural design to achieve fire resistance, for elements made of different materials (steel, concrete, timber) and subject to various effects of actions (tension, compression and bending moment).
(iv) Achieving fire resistance in real projects. The course mobilizes the techniques and knowledge gained in the previous parts to analyze how structural fire resistance can be achieved in real projects, in an economic and sustainable way. Attention is paid to various methods of protection of structures to fire as well as on performance-based design taking advantage of, for instance, tensile membrane action. Examples are presented from the experience of the teaching team as consultants.

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

At the end of this class, the student will be able to design a building taking into account the fire loading scenario. She/He will have the tools that allow ensuring a safe design, not only in accordance with code prescriptions, but also with innovative concepts that can allow significant cost savings compared to traditional approaches. 
More globally, the student will acquire some knowledge of the fire physics and the fire safety engineering field, as well as improve its knowledge in the field of structural mechanics.

Savoirs et compétences prérequis

Good understanding of strength of materials and of structural mechanics is required. Basic knowledge on the behaviour of structures made of steel, concrete and timber is required.

Activités d'apprentissage prévues et méthodes d'enseignement

Frontal lectures will be given for the theorerical part.
Tutorials will be organized for the practical part, where exercices are either demonstrated to the students or to be done by them, about the design of structural elements subjected to fire.

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

The course is given face to face except if the ratio "number of seat available/number of students" is to low with regards to COVID situation, in which case the teaching mode will be adapted

Adaptations organisationnelles liées au contexte sanitaire

Lectures recommandées ou obligatoires et notes de cours

Reference to interesting books or literature papers will be given during the lectures. To prepare the exam, the students will have a copy of all the PowerPoint presentations used for the lectures through MyULg.

Modalités d'évaluation et critères

Vous trouverez ci-dessous les modalités d'évaluation envisagées pour les examens en présentiel et à distance ainsi que celle souhaitée en cas de session hybride. En fonction de l'évolution sanitaire, la modalité choisie vous sera communiquée au plus tard un mois avant le début de la session d'examen.

40% for the written exam, organised at the end of the course, consisting in practical questions (exercices based on the tutorials).
60 % for the oral Examination, organised at the end of the course, on the topics covered during the lectures.
