Main themes

Any building is subject, during the period between its construction and demolition, to a series of actions (anthropic or environmental) that lead to a progressive degradation of its materials and a decrease in its resistance.
The General Socio-Economic Survey (ESE 2001) allowed to highlight, through the elaboration of an indicator that evaluates the physical and structural condition of buildings, that about 13% of the Belgian constructions need at least a major repair.
The objective of this course is to give an overview, as far as possible, of the problems related to the rehabilitation of buildings. In order to achieve this objective, the course will focus on the understanding of the resistance mechanisms of constructions, the analysis of the state of damage (level of damage and causes that generated it) and the definition of intervention methods capable of bringing the construction back to the level of safety required by the existing regulations.

.	Contribution of the course to the program objectives: AA 1.1, AA 1.2, et AA 1.3 At the end of this learning unit, the student is able to: More specifically, at the end of the course, the student will be able to: - Prepare an expertise report on a structure that shows signs of degradation, and propose sustainable, inexpensive solutions that have a minimal impact on the structure's usability.

Content

The course aims to present a series of topics that, due to lack of time, are not usually covered in classical courses on stability and design of buildings, such as: mechanical behavior of masonry, statics of masonry arches, analysis of cracks, characteristics of materials used for consolidation, mathematical models of the evolution of degradation, the most common methods and instruments of measurement in situ and in the laboratory, evaluation of the life cycle of a structure.
As a tentative outline, the course will consist of 24 hours of ex-cathedra lectures covering both theoretical and computational aspects. These lectures will cover the following topics:
Introduction to aspects of building pathology and rehabilitation.
Static behavior of masonry.
Structural pathologies in masonry constructions.
Static behavior and pathologies of masonry arches.
Physical and mathematical modeling of degradation in reinforced concrete and steel constructions.
Laboratory measurements.
Building materials for rehabilitation.
Rehabilitation techniques for masonry constructions.
Rehabilitation techniques for reinforced concrete constructions.
Rehabilitation techniques for steel and wood constructions.
Evaluation of the structural safety of bridges.
Evaluation of the residual life of bridges.
These lectures will be completed by approximately 6 hours of seminars given by practicing engineers or visiting professors.

Teaching methods

Ex-cathedra teaching given by the teacher, combined with seminars (about 6 hours) given by practicing engineers or visiting professors.

Evaluation methods

Each student is orally examined, after a period of preparation.

Online resources

Available on Moodle.
