WCCM8 MINI-SYMPOSIUM ID 63:
MODELING ROBUSTNESS AND STRUCTURAL RELIABILITY ANALYSIS

James L. Beck*, Gerhart I. Schuëller AND Héctor A. Jensen#

Robustness in the prediction of structural response is an essential requirement of structural analysis for quality assurance. Errors in predictions can arise from many possible sources, such as uncertainty and variability in the structural boundary conditions, loads and material properties, and incomplete model capabilities. During design and operation, the acceptable, or desired, structural performance is usually defined in terms of specified response quantities not exceeding certain limits, such as interstory drift limits or floor acceleration limits. To assess the structural performance, it is important that robust predictions are made that treat all the uncertainties, from modelling future loads to modelling the structural behaviour. This leads naturally to the concept of robust reliability which quantifies the confidence that the analyst has that the design, when constructed, will meet the design specifications. Maximization of the robust reliability could be used, for example, to search for an optimal robust design among a feasible set of designs.

12th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference

10-12 September 2008
Victoria Conference Centre, Victoria, British Columbia, Canada

For over twenty years, the biennial AIAA/ISSMO Multidisciplinary Analysis and Optimization (MA&O) Conference has brought together industry practitioners, government employees, and academics to present and discuss the latest developments in multidisciplinary design, analysis, and optimization. Multidisciplinary analysis and optimization is rapidly becoming a standard element of contemporary design methodologies. With significant advances in computing algorithms and power, impressive analysis and optimization applications have been successfully carried out in industry, government, and academia alike. Additionally, theoretical developments ranging from new optimization algorithms to approaches for design system robustness and reliability have played a significant role in the ever-growing acceptance of multidisciplinary design and optimization. Historically, the MA&O Conference has provided a comprehensive view of the state-of-the-art. For the first time in its history, the MA&O Conference will be held outside the United States.

News Research Positions in Fuzzy Finite Elements

Several PhD and post-doctoral research positions are currently vacant within the framework of a recently started SBO-project of the Institute for the Promotion of Innovation by Science and Technology in Flanders, Belgium (IWT, www.iwt.be).

This 4-year project involves the study and development of methods for dealing with uncertainty in finite element calculations. More specifically, this project aims at the development of a generic approach for implementing a fuzzy finite element method. It also focusses on the possible extension of this approach to other non-probabilistic or hybrid non-deterministic techniques, as e.g. imprecise probabilities, info-gap and probability boxes. Next to the development of algorithms and numerical implementation strategies, the project focuses explicitly on the actual application of these novel non-deterministic numerical simulation techniques for design purposes.

This project assembles a consortium of eight prominent Flemish partners with academic as well as industrial background in the field of non-deterministic numerical modeling techniques. Vacancies for PhD students as well as post-doctoral researchers are currently available at the five involved academic research partners in two leading Flemish universities:

Objectives

The 2008 Leuven Conference on Noise and Vibration Engineering will be held from September 15th till 17th in Leuven, Belgium. It is the 23rd international conference in a series of annual courses and biennial conferences on structural dynamics, modal analysis and noise and vibration engineering, organised by the Department of Mechanical Engineering of the Katholieke Universiteit Leuven.

The conference provides a forum for engineers, researchers and other professionals active in the field of modelling, analysing, testing and improving the noise and vibration characteristics of mechanical systems and civil structures. The conference combines expertise in the noise and vibration fields by stressing common measurement, modelling, analysis and control technologies. The meeting will provide a further impetus to the cross fertilisation of ideas in both areas

Course on "Risk Analysis and Structural Reliability"

26-28 November 2007, Paris, France

http://www.asranet.com/ 

The course aims to provide participants with an understanding of the fundamental elements of risk analysis and structural reliability. It will also introduce the concepts of uncertainty modelling in load and strength applications. Practical applications for the safety assessment of engineering structures, considering the key techniques involved, will be highlighted. Emphasis will be on the use of reliability engineering methods in offshore and marine structures.

The syllabus will include: basic elements of the safety case concept, hazard identification techniques, risk assessment, risk reduction, safety management systems, uncertainties in load and strength predictions, structural reliability and the goal-setting approach to safety. The course is intended for practising engineers and research scientists who need to understand the concepts behind risk analysis and structural reliability, to interact with experts in safety management or to begin to undertake a more extensive study of the subject.
