Offer 1 with catalog number 4023992ENR for all students in the 1st semester at a (E) Master - advanced level.
The course studies the time dependent behavior of structures and systems excited by dynamic forces. The course starts with the analysis of systems with one, two and several degrees of freedom, with and without damping, and also deals with simple continuous structures (beams and bars) and more complex finite element models. The different sources of excitations for practical applications are described, together with a description of the effects and a discussion of possible design and remedial measures. Sensors, data acquisition and signal processing to measure vibrations experimentally are also presented.
The course is articulated around different case studies for which the students will learn to describe the source of excitation, how to model the problem and predict vibration levels, as well as propose the most adequate design and remedial measures when these levels are excessive.
The course consists of 24h of lectures based on the principle of flipped classes. The students are asked to watch one or several short videos before the class, and the time in the class is dedicated to interactive activities such as wooclap sessions, group exercises and discussions about case studies to consolidate the theoretical knowledge.
Videos are made available prior to the lessons a.o. via structuraldynamics.ulb.be. All additional information is made available through Canvas. Registration to Canvas is required to participate in the exercise sessions.
The exercise sessions are organized in 6 sessions (24h) using Jupyter Notebooks (Python). Exercise sessions will conclude with an individual project (12h) to be performed at home, which is defended individually during the oral examination.
The exercises are aimed at illustrating the theoretical concepts and to prepare for the final project: understanding of the excitation (based on Fourier analysis), modeling of the physical system (including reduction to a single degree of freedom system), computation of the response both in time and frequency domain, assessment of potential dynamic instabilities
The students will learn how to model time dependent dynamic behavior of structures. Emphasis is put on the ability to derive simple models from real complex structures and to compute their dynamic response due to different types of excitations.
The students will also develop a deep understanding of the sources and effects of vibrations on structures, as well as basics on instrumentation and methods to measure vibration levels, frequency response functions, and extract modal data on real structures.
When measured or predicted vibration levels are excessive, the students will learn what are the most relevant redesign and remedial measures and how to apply them, with a design oriented approach.
Having in-depth knowledge and understanding of the advanced methods and theories to schematize and model complex problems or processes.
Can reformulate complex engineering problems in order to solve them (simplifying assumptions, reducing complexity).
Can correctly report on research or design results in the form of a technical report or in the form of a scientific paper.
Can present and defend results in a scientifically sound way, using contemporary communication tools, for a national as well as for an international professional or lay audience.
The final grade is composed based on the following categories:
Oral Exam determines 80% of the final mark.
PRAC Report determines 20% of the final mark.
Within the Oral Exam category, the following assignments need to be completed:
Within the PRAC Report category, the following assignments need to be completed:
Timely submission of all 6 completed exercise sessions through the designated portal is required and accounts for 20% of the final mark. The oral examination is split in two parts, a first part with questions related to the theoretical part of the course, and a second part dedicated to the defense of the individual project. Each part accounts for 40% of the total mark.
