title = "A hybrid method for the vulnerability assessment of R/C and URM buildings",
abstract = "The methodology followed by the Aristotle University (AUTh) team for the vulnerability assessment of reinforced concrete (R/C) and unreinforced masonry (URM) structures is presented. The paper focuses on the derivation of vulnerability (fragility) curves in terms of peak ground acceleration (PGA), as well as spectral displacement (s d), and also includes the estimation of capacity curves, for several R/C and URM building types. The vulnerability assessment methodology is based on the hybrid approach developed at AUTh, which combines statistical data with appropriately processed (utilising repair cost models) results from nonlinear dynamic or static analyses, that permit extrapolation of statistical data to PGA's and/or spectral displacements for which no data are available. The statistical data used herein are from earthquake-damaged greek buildings. An extensive numerical study is carried out, wherein a large number of building types (representing most of the common typologies in S. Europe) are modelled and analysed. Vulnerability curves for several damage states are then derived using the aforementioned hybrid approach. These curves are subsequently used in combination with the mean spectrum of the Microzonation study of Thessaloniki as the basis for the derivation of new vulnerability curves involving spectral quantities. Pushover curves are derived for all building types, then reduced to standard capacity curves, and can easily be used together with the S d fragility curves as an alternative for developing seismic risk scenarios.",

note = "Funding Information: Acknowledgements Most of the work reported in this paper was carried out by the writers within the framework of the RISK-UE project, funded by the European Commission. The last part of the dynamic time-history analyses of R/C buildings was carried out after the end of the RISK-UE project, within the frame of a nationally funded (by the General Secretariat of Research and Technology of Greece) project, ARISTION (started in Oct. 2003), concerning the vulnerability of the building stock of R/C and masonry buildings in Greece, and the development of seismic retrofit techniques using new materials. The writers wish to acknowledge the assistance of Prof. K. Stylianidis (AUTh) and his contribution in the vulnerability assessment of the URM buildings, particularly in the selection of generic building to be analysed, of Prof. S. Lagomarsino (Univ. of Genoa) for his contribution to the proper interpretation of available damage statistics for URM buildings and for sharing with the writers his experience from the vulnerability assessment of the italian masonry building stock, and of Prof. K. Pitilakis (AUTh) for making available to the writers data from the microzonation study of Thessaloniki carried out by his group. Last and not least, the fruitful discussions with, and the critical comments of, all members of the RISK-UE teams that contributed to the WP4 activities was a major stimulus for the writers and guided them in improving their existing models and integrating them within the broader scope of the RISK-UE project.",
