Learning unit contents
COMPOSITE CONSTRUCTIONS: A structural element of a construction is defined as composite if it is associating two materials of different nature and/or with different properties. The objective with a composite construction is to extract, from a mechanical point of view, the best contributions from the materials involved in this association. The most usual case in composite construction is the one associating steel and concrete. This is this type of composite construction which is considered within this course. The concrete and the steel, materials fundamentally different, are perfectly compatible and complementary. They constitute a perfect combination from the resistance point of view: concrete is very efficient to sustain compression while steel is substituted to concrete to sustain tension. Concrete also ensures a protection against corrosion and a thermal insulation for steel at elevated temperature. Moreover, it can stiffen slender sections for instability phenomena which may occur in elements partially or totally under compression. The actual practice in Europe demonstrates clearly that the composite construction can be competitive, in terms of global cost, if compared to « classical » steel or concrete constructions. In particular, for multi-storey buildings, it is true for cases with long span (12 m to 15 m) between columns, long span slabs or when a simple and rapid construction way on site is required. Consequently, in the domain of buildings, the composite solution may demonstrate mechanical, economical and architectural interests. Within the present course, the main design and application rules for composite beams, slabs and columns (used as structural elements in buildings) will be presented. STEEL CONSTRUCTIONS: The course is inscribed in the continuity of lectures given in third Bachelor, option "Constructions" (Calculation of Steel Elements) and of the here-above described course on "Composite Constructionss". The steel and composite constructions are here studied in terms of global structural response and no more only in terms of structural elements. The notions of analyses become very important. The first order and second ordre analysis methods and elastic/plastic analyses arel so be applied to building frames. The concept of rigid/semi-rigid joints is investigated. A particular attention is also paid to constructions with thin-walled members. Finally, aspects of fatigue and weld design are covered.
Learning outcomes of the learning unit
At the end of the lecture and the group exercices, the student will be able to design steel and steel-concrete composite structures, with account of the actual behaviour of joints. He will also be able to deal with constructions made of thin members.
The complete list of the KLO for this course is defined in the matrix available at the following address: https://www.programmes.uliege.be/cocoon/20182019/formations/descr/A2UCON01.html
Prerequisite knowledge and skills
Some basic knowledge in the following domain is required:
- Mechanic of materials
- Mechanic of structures
- Steel constructions
- Concrete constructions
Planned learning activities and teaching methods
Learning activities within this lecture:
- Theoretical lessons: attendance recommended but not mandatory
- Lessons with exercises: Attendance MANDATORY
- Exercise in group: this MANDATORY work consists in designing a building structures using the concepts seen during the theoritical and exercises lessons and others to be learned by yourself
Mode of delivery (face-to-face ; distance-learning)
The courses are given face-to-face.
The course will be given in the second semester.
Recommended or required readings
For this lecture, a set of documents covering the topic of the lecture will be given to the students. Also, the PowerPoint presentations used as a support for the theoretical lectures will be made available under a PDF format.
Assessment methods and criteria
At the end of the exercise in group, a hand-written computation note will have to be delivered by the students and will be evaluated. This evaluation will be taken into account to establish the final quotation for this course.
This activity is inseparable from the teaching unit and considered as compulsory. A student who has not participated in this activity and / or who has not submitted the expected report within the prescribed deadlines or in the prescribed forms will not be allowed to present the examination.
The fact of not having the report does not allow to evaluate the work of the student. So, a mark "A" will be attributed in this case (except if a specific justification is provided and accepted by the professors which will analyse the justificiation with equity).
In first session, an oral examination will be organised during which theoritical and practical questions will be asked.
For the theory, a particular attention will be paid to the understanding of the physic of the phenomena rather than a restitution of the content of the lecture
For the second session, an oral examination as for fiirst session will be also organised
The final mark for this course will be fixed with the following subdivision:
First session: 15% for the exercise in group and 85% for the oral exam
Second session: 15% for the exercise in group and 85% for the oral exam
Work placement(s)
Organizational remarks
General remark: 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 Master thesis.

Adaptation of teaching commitments following the COVID-19 pandemic for the May-June 2020 session
Teaching methods implemented : distance-learning
E-learning through the use of commented PowerPoint presentations and the use of reference documents.
A questions and answers session by videoconference is organized on April 22, 2020 starting at 13h30.
The professors and the assistant are available to students through a forum created at this occasion but also by email or videoconference to answer all questions relating to the subjects taught.
Assessment subjects
The content of evaluation is identical to the one intitally planned.
Assessment methods
Due to the confinment measures taken by the Belgian government and taking into account the recommendations of our institution and our faculty, the evaluation methods during the first session of May-June are modified as follows:
- The oral examination is replaced by a written examination to be carried out at home with surveillance by videoconference;
- As for the oral exam initially planned, theoretical reflective questions will be asked and possible small exercises will be submitted to students during this written exam;
- This examination will be carried out during the May-June examination session in accordance with the faculty calendar, i.e. on June 17, 2020, in the morning;
- This examination will be carried out with an open book;
- The use of electronic tools will not be authorized during the exam except to access to the surveillance by videoconference;
- The modalities of connection to the surveillance by videoconference will be communicated to you by the Professors in due time;
- A PDF copy must be sent to the Professors by email at the end of the exam and this, within a limited time. The tool for making this PDF copy using a smartphone will be specified.
A try of the exam procedure will be organised during the week of May 11 2020.
More details on the practical details of the examination will be communicated in due time.
The distribution percentages of the ratings between the project part and the exam part are modified in order to take into account the difficulties generated by home working. The final mark will be distributed as follows: 25% for the project and 75% for the exam, and this only for students for whom the project will have a favorable impact on the final mark. If this is not the case, the initially planned percentages, namely 15% for the project and 85% for the examination, will be maintained
If the containment measures were to be maintained until the organization of the second session, the same methods of examination would be adopted.
