101-0178-01LUncertainty Quantification in Engineering Information W3 KP2GS. Marelli
KurzbeschreibungUncertainty quantification aims at studying the impact of aleatory and epistemic uncertainty onto computational models used in science and engineering. The course introduces the basic concepts of uncertainty quantification: probabilistic modelling of data (copula theory), uncertainty propagation techniques (Monte Carlo simulation, polynomial chaos expansions), and sensitivity analysis.
LernzielAfter this course students will be able to properly pose an uncertainty quantification problem, select the appropriate computational methods and interpret the results in meaningful statements for field scientists, engineers and decision makers. The course is suitable for any master/Ph.D. student in engineering or natural sciences, physics, mathematics, computer science with a basic knowledge in probability theory.
InhaltThe course introduces uncertainty quantification through a set of practical case studies that come from civil, mechanical, nuclear and electrical engineering, from which a general framework is introduced. The course in then divided into three blocks: probabilistic modelling (introduction to copula theory), uncertainty propagation (Monte Carlo simulation and polynomial chaos expansions) and sensitivity analysis (correlation measures, Sobol' indices). Each block contains lectures and tutorials using Matlab and the in-house software UQLab (Link).
SkriptDetailed slides are provided for each lecture. A printed script gathering all the lecture slides may be bought at the beginning of the semester.
Voraussetzungen / BesonderesA basic background in probability theory and statistics (bachelor level) is required. A summary of useful notions will be handed out at the beginning of the course.

101-0008-00LStructural Identification and Health MonitoringW3 KP2GE. Chatzi, V. Ntertimanis
KurzbeschreibungThis course will present methods for assessing the condition of structures based on monitoring. The term "monitoring" corresponds to measurements of structural response (e.g. strains, deflections, accelerations), which are nowadays available from low-cost and easily deployed sensor technologies. We show how to exploit sensing technology for maintaining a safe and resilient infrastructure.
LernzielThis course aims at providing a graduate level introduction into the identification and condition assessment of structural systems.

Upon completion of the course, the students will be able to:
1. Test Structural Systems for assessing their condition, as this is expressed through stiffness
2. Analyse sensor signals for identifying characteristic structural properties, such as frequencies, mode shapes and damping, based on noisy or incomplete measurements of the structural response.
3. Establish relationships governing structural response (e.g. dynamics equations)
4. Identify possible damage into the structure by picking up statistical changes in the structural "signature" (behavior)
InhaltThe course will include theory and algorithms for system identification, programming assignments, as well as laboratory and field testing, thereby offering a well-rounded overview of the ways in which we may extract response data from structures.

The topics to be covered are :

1. Fundamentals of dynamic analysis (vibrations)
2. Fundamentals of signal processing
3. Modal Testing for determining the modal properties of Structural Systems
4. Parametric & Nonparametric Identification for processing test and measurement data
i) in the frequency domain (Spectral Analysis, Frequency Domain decomposition)
ii) in the time domain (Autoregressive models, the Kalman Filter)
5. Damage Detection via Stochastic Methods

A comprehensive series of computer/lab exercises and in-class demonstrations will take place, providing a "hands-on" feel for the course topics.

Grading:
The final grade will be obtained, either
- by 30% from the graded exercises and 70% from the written session examination, or
- by the written session examination exclusively.
The highest ranking of the above two options will be used, so that assignments are only used to strengthen the grade.

101-0194-00LSeismic Evaluation and Retrofitting of Existing StructuresW2 KP1GA. Tsiavos
KurzbeschreibungThe aim of this course is to present the state of the art of the current procedures for seismic evaluation and retrofitting of existing structures in Switzerland (Norm SIA 269/8) and worldwide. Emphasis will be given on the practical application of these procedures in real structures located in Switzerland, through case studies presented by experts in the field.
LernzielA large percentage of the existing building inventory worldwide has been constructed before the introduction of the current seismic code provisions. The seismic deficiencies observed in many of these structures are a direct outcome of their non-compliance with these provisions and the established engineering practices in seismic design. Moreover, the unavoidable material deterioration in these structures could further inhibit their seismic performance. Therefore, the knowledge of the current procedures and common practices for the seismic evaluation and retrofitting of structures is of paramount importance. This course presents an overview of these procedures through a wide spectrum of applied case studies in Switzerland and worldwide. The students will work on a project related to the presented case studies, thus obtaining deep understanding on the application of these procedures and a feeling on how to engineer practical retrofitting strategies towards the seismic upgrading of existing structures.
Inhalt1. Introduction to seismic hazard and seismic performance objectives.
2. Common structural deficiencies and observed damage patterns due to strong earthquake ground motion excitation.
3. Seismic evaluation of structures in Switzerland using Norm SIA 269/8: Presentation of the code in steps and discussion of the critical issues.
4. Seismic retrofitting of structures in Switzerland using Norm SIA 269/8: Presentation of the code in steps and discussion of the critical issues.
5. Application of seismic evaluation using SIA 269/8 on an existing structure in Switzerland.
6. Application of seismic retrofitting using SIA 269/8 on an existing structure in Switzerland.
7. Seismic evaluation methodologies worldwide: State of the art. Presentation of illustrative examples.
8. Introduction to Yield Point Spectra and the Constant Yield Displacement Evaluation (CYDE) method.
