Abstract
Earthquake vulnerability is a major contributor to seismic risk, while vulnerability assessment is an essential tool for the identification and mitigation of earthquake losses. Over the last years, significant research work has been made towards the development of a comprehensive methodology regarding the estimation of the expected earthquake losses and the resilience of man-made structures, while researchers have developed analytical, empirical, judgment-based and hybrid fragility curves covering a wide variety of structural typologies. To date, fragility curves are derived assuming fixed-base conditions, ignoring soil-structure interaction (SSI) and local site effects, yet these effects may play either a beneficial or a detrimental role to the seismic response of the structures. In this context, the influence of (i) SSI and (ii) nonlinear soil behavior on earthquake vulnerability assessment of structures needs further investigation. This lecture is built upon this scientific shortage, discussing efficient approaches to tackle the ever-emerging problem of the earthquake vulnerability assessment of civil engineering soil - foundation - structure systems.
Bio
Dimitris Pitilakis is Associate Professor in the Department of Civil Engineering of the Aristotle University of Thessaloniki, Greece (M.Sc. University of California, Berkeley, Ph.D. in earthquake engineering from Ecole Centrale Paris, France). He is an expert in geotechnical earthquake engineering, with emphasis on soil – foundation – structure interaction, dynamics of foundations and performance-based design. Lately, he has been working on the earthquake vulnerability assessment of soil-foundation-structure systems, in local and in city scale. He is a member of national and international scientific societies on Earthquake Engineering and reviewer of international scientific journals. He has developed software for the simulation of the soil- foundation- structure interaction, with emphasis on nonlinear soil behavior, as well as software for foundation design and analysis. He has significant experience in experimental soil-foundation-structure interaction in small-scale (shaking table and centrifuge) and full-scale (EuroProteas in Euroseistest http://euroseisdb.civil.auth.gr/sfsis) facilities. He is currently in charge of the shaking table facility of the Aristotle University of Thessaloniki, and of the full-scale EuroProteas facility.
