D 3.5 DELIVERABLE PROJECT INFORMATION Systemic Seismic Vulnerability and Risk Analysis for Project Title: Buildings, Lifeline Networks and Infrastructures Safety Gain Acronym: SYNER-G Project N°: 244061 Call N°: FP7-ENV-2009-1 Project start: 01 November 2009 Project end: 31 October 2012 DELIVERABLE INFORMATION D3.5 - Fragility functions for water and waste-water Deliverable Title: system elements Date of issue: 31 October 2010 Work Package: WP3 – Fragility functions of elements at risk Deliverable/Task Leader: Aristotle University of Thessaloniki (AUTH) Reviewer: Norwegian Geotechnical Institute (NGI) REVISION: Final Project Coordinator: Prof. Kyriazis Pitilakis Institution: Aristotle University of Thessaloniki e-mail: [email protected] fax: + 30 2310 995619 telephone: + 30 2310 995693 Abstract This deliverable provides the technical report on the assessment of fragility functions for water and waste-water system elements. This deliverable comprises four main parts. A short review of past earthquake damages on water and waste-water system elements is provided in the first part, including the description of physical damages, the identification of main causes of damage and the classification of failure modes. The following two parts deal with the identification of the main typologies of water and waste-water system components and the general description of existing methodologies, damage states definitions, intensity indexes and performance indicators of the elements. In the next part the validation of the available vulnerability functions for pipes is provided based on damage data from recent European earthquakes (Düzce and Lefkas). Finally, improved vulnerability functions for the individual components are proposed along with the coding and digital description of fragility functions. Keywords: fragility functions, vulnerability, water system, waste-water system i Acknowledgments The research leading to these results has received funding from the European Community's Seventh Framework Programme [FP7/2007-2013] under grant agreement n° 244061. iii Deliverable Contributors [AUTH] Alexoudi Maria, Dr. Civil Engineer, MSc Kyriazis Pitilakis, Professor Argyro Souli, Civil
