101-0178-01LUncertainty Quantification in Engineering Information W3 KP2GS. Marelli, B. Sudret
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 (www.uqlab.com).
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.

Upon completion of the course, the students will be able to:
1. Test Structural Systems for assessing their condition, as this is expressed through measurements of dynamic response.
2. Analyse vibration signals for identifying characteristic structural properties, such as frequencies, mode shapes and damping, based on noisy measurements of the structural response.
3. Formulate structural equations in the time and frequency domain
4. Identify possible damage into the structure by picking up statistical changes in the structural 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. Elements of Vibration Theory
2. Transform Domain Methods
3. Digital Signals (P
4. Nonparametric Identification for processing test and measurement data
(transient, correlation, spectral analysis)
5. Parametric Identification (time series analysis, transfer functions)

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

101-0194-00LSeismic Evaluation and Retrofitting of Existing BuildingsW2 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 buildings in Switzerland (Norm SIA 269/8) and worldwide. Emphasis will be given on the practical application of these procedures in real buildings 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 buildings 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 buildings.
Inhalt1. Introduction to seismic hazard and seismic performance objectives.
2. Common structural deficiencies and observed damage patterns in buildings due to strong earthquake ground motion excitation.
3. Seismic evaluation of buildings in Switzerland using Norm SIA 269/8: Presentation of the code in steps and discussion of the critical issues.
4. Seismic retrofitting of buildings 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 building in Switzerland.
6. Application of seismic retrofitting using SIA 269/8 on an existing building in Switzerland.
7. Seismic evaluation methodologies worldwide: State of the art. Presentation of illustrative examples.

101-0194-10LSeismic Design and Evaluation of BridgesW2 KP2GA. Tsiavos
KurzbeschreibungThe aim of this course is to provide the fundamental knowledge on the seismic design and evaluation of bridges in Switzerland and worldwide. The course focuses on the practical application of this knowledge through the seismic design and evaluation of real bridges located in Switzerland.
LernzielThe existing bridge inventory in Switzerland consists of about 3340 bridges, facilitating the continuous function of the national highway transportation network. Furthermore, a large number of new bridges are under construction in Switzerland. These bridges serve as intermediate links, connecting different communities and enabling the accessibility of different infrastructure components. Within this frame, the seismic protection of new and existing bridges is critical for the maintenance of the functionality of our communities and their ability to recover after a strong earthquake event. Along these lines, this course aims to provide knowledge of the latest code provisions and analysis methods for the seismic design and evaluation of bridges in Switzerland and worldwide. This knowledge will be provided through a combination of theoretical background with practical case study examples. The students will work on a project related to the presented case studies, thus obtaining hands-on experience in the seismic evaluation and seismic retrofitting of existing bridges located in Switzerland.
