This database was compiled by SERIES (www.dap.series.upatras.gr) and it has been reproduced here to preserve the data and ensure continued access. It includes material and geometric properties, experimental results, digital load-deflection records and references for tests of reinforced concrete structural walls. The SERIES RC Wall Database provides researchers with data needed to evaluate and develop seismic performance models for RC walls.

The version of the database presented here was last updated in July 2013.

This database builds on previous work carried out at the University of Washington (PEER database), University of Patras (Biskinis et al, 2004, Biskinis & Fardis 2010a, 2010b, Panagiotakos and Fardis, 2001), Stanford University (Lignos and Krawinkler, 2009) and University of Ljubljana (Peruš, Poljanšek and Fajfar, 2006; Poljanšek, Peruš and Fajfar, 2008). Other partners are UPAT, EUCENTRE, ITU, IZIIS, LNEC, NTUA, TU IASI, UNAP, UNITN, UCAM and UOXF, IFSTTAR, METU, UNIVBRIS.

Parameter definitions are listed in the sections below.
