    • ICOSSAR 2013, Columbia University, New York, 16-20 June 201311thInternational Conference on Structural Safety & Reliability (ICOSSAR 2013)June 16-20, 2013, Columbia University, New York, NY (http://icossar2013.org/)CALL FOR PAPERS FOR A MINI-SYMPOSIUM ONPerformance-Based, Reliability-Based, and Risk-Based Design:Rational approaches to mitigate natural and man-made hazardsCo- sponsored by: SEI-ASCE Multi-Hazard Mitigation Committee andSEI-ASCE Performance-Based Design for Structures CommitteeMitigation of natural and man-made hazards is one of the major goals of structural engineering. In the lastfew decades, several methodologies have been developed and/or formalized to achieve this aim, e.g.,performance-based design, reliability-based design, and risk-based design. While these approaches havedifferent focuses, they have in common the explicit and rational consideration of the uncertainties thatinherently affect loading environment, mechanical properties of structural materials, boundary conditions,modeling assumptions, construction procedures, and other relevant types of aleatory and epistemicuncertainties. In addition, formally different approaches can be used in combined frameworks, e.g.,reliability-based optimization in the context of performance-based earthquake engineering.This mini-symposium provides the opportunity to present current research efforts and findings in the contextof performance-based, reliability-based, and risk-based design of engineering systems subjected to naturaland man-made hazards. Contributions addressing both theoretical developments and practical applicationsfrom different sub-fields of structural engineering (e.g., earthquake, wind, hurricane, fire, offshore,aerospace, blast engineering) are welcome. This mini-symposium aims to provide an overview of state-of-the-art methods, standards, theoretical advances, and case studies, and to identify ways for furtherdevelopments of rational approaches to mitigate single and/or multiple natural and/or man-made hazards,with explicit consideration of uncertainties. Therefore, the mini-symposium will provide an opportunity tobring together researchers, academics, design code developers, and practicing engineers active in thesetopical areas to share their experience and latest results, with particular focus on real-world applications.Keywords: Performance-Based Design, Reliability-Based Design, Risk-Based Design, Natural and man-made hazards, Uncertainty quantification.Proposed by:
