EPFL and DTU are both members of the Eurotech University Alliance together with Technische Universiteit Eindhoven and Techische Universität München. One of the aims of this partnership concerns research collaborations within the European dimension, hereunder the HORIZON 2020 program. With the purpose of enhancing the research collaborations between the Civil Engineering Departments of EPFL and DTU the first part of the presentation thus aims to provide an overview of some of the main research interests and activities of DTU Civil Engineering.
Structural Health Monitoring (SHM) has, over the last 2-3 decades, become a topic of significant interest within the structural engineering research community, but also in the broader areas of civil and mechanical engineering. Whereas the merits of health monitoring are generally appreciated in qualitative terms there has, as of yet, not been reported much fundamental research on the quantification of the benefit of SHM. The present presentation, addresses the quantification of the value of SHM taking basis in the Bayesian pre-posterior decision analysis and the concept of Value of Information (VoI) analysis.
Starting point is taken in the identification of different typical situations in structural engineering in which health monitoring would have the potential to provide value beyond its costs. Subsequently, the theoretical framework which allows for the quantification of its value is shortly summarized and illustrated on a principal example. Subsequently, the use of the VoI concept in optimization of inspection and maintenance strategies of fatigue sensitive details in welded connections of offshore structures is illustrated and finally a potential framework for future collaborations within the EU COST Action program is outlined.
Bio: Michael Havbro Faber is professor in Risk and Safety and the head of the department of civil engineering at the Technical University of Denmark, DTU.
His research is directed on engineering decision making with focus on applied Bayesian decision theory, life safety, management of catastrophic risks, risk assessment, Bayesian uncertainty modeling, structural reliability and risk based assessment and maintenance. During his career Michael H. Faber has engaged continuously in industrial projects and acts as a consultant in ongoing projects related to offshore safety and reliability, transport risk and life safety assessments as well as natural hazards risks management.
Michael H. Faber is a member of the Danish Academy of Technical Sciences and is actively involved in several international committees, including: The Joint Committee on Structural Safety (vice-president); the International Forum on Engineering Decision Making (founding president); the Civil Engineering Risk and Reliability Association (chair) and alumni of the WEF GAC on Catastrophic Risks.
