Alfred Strauss, Ph.D., P.E., F. ASCE, is Professor of Structural Mechanics at University of Natural Resources and Life Sciences since 2008. He received a Professor Qualification (Scientific Habilitation) from the University in 2013. His education includes a 5yr Degree in Civil Engineering with honors from the Technical University of Vienna (1997), a PhD in Stochastic-Probabilistic Engineering from University of Natural Resources and Life Sciences (2004). He is an experienced researcher and consultant engineer for advanced structural analysis problems related to bridges, roof systems, and off shore structures. His main research areas include computational analysis of concrete structures, structural reliability, structural optimization, life-cycle engineering, artificial intelligence in structural engineering.
Abstract
International activities associated with the lifetime performance of existing infrastructure systems
In recent years, life-cycle analyses methods becoming more and more attractive for the assessment of new and existing infrastructures, as well as for the evaluation of maintenance strategies. Associated management systems, capturing different degradation processes, are very often used in relation to such life-cycle analyses methods. Such systems, developed for a structural condition assessment, are usually based on deterministic or probabilistic performance prediction models which describe the future condition by a functional correlation between structural condition attributes, such as the structural age, and the mechanical, chemical and thermal loading processes.
With respect to these developments, there are a lot of associated national and international activities dedicated to enhance existing methods and develop new tools for an economically efficient, environment-friendly, and socially reconcilable decision-making process on existing bridges and other structures.
The objective of this life talk is (a) the critical discussion of processes to enhance previously mentioned methods that allow for instance the definition of intervention strategies for different types of structures including the different levels of data availability, and (b) to present the various strategies and activities in international associations like fib and IABSE to include the newest achievements from European research projects in engineering practice and guidelines.
