This paper presents REXELite, an internet version, operating on the ITalian ACcelerometric Archive (ITACA), of REXEL, a software developed for automatic selection of ground motion suites for nonlinear dynamic analysis of structures. REXELite allows to search for horizontal combinations of seven 1- or 2-components strong motion records, compatible on average with a specified target spectrum. More specifically, REXELite: (1) automatically builds code spectra for any limit-state according to Eurocode 8 and the new Italian building code; (2) searches, in ITACA, the set of seven records having the most similar spectral shape with respect to that of the code, and whose average also matches the target spectrum in a user-specified period range and with the desired tolerance. The records are selected according to specific features, in terms of magnitude, distance and soil conditions, selected by the user. The set of accelerograms of the combination may include unscaled (original) or amplitude-scaled records. REXELite was developed, by the authors, as a partnership of ReLUIS (Rete dei Laboratori Universitari di Ingegneria Sismica) and the INGV (Istituto Nazionale di Geofisica e Vulcanologia) within the S4 Project funded by the Italian DPC (Dipartimento della Protezione Civile).

Abstract

This paper presents REXELite, an internet version, operating on the ITalian ACcelerometric Archive (ITACA), of REXEL, a software developed for automatic selection of ground motion suites for nonlinear dynamic analysis of structures. REXELite allows to search for horizontal combinations of seven 1- or 2-components strong motion records, compatible on average with a specified target spectrum. More specifically, REXELite: (1) automatically builds code spectra for any limit-state according to Eurocode 8 and the new Italian building code; (2) searches, in ITACA, the set of seven records having the most similar spectral shape with respect to that of the code, and whose average also matches the target spectrum in a user-specified period range and with the desired tolerance. The records are selected according to specific features, in terms of magnitude, distance and soil conditions, selected by the user. The set of accelerograms of the combination may include unscaled (original) or amplitude-scaled records. REXELite was developed, by the authors, as a partnership of ReLUIS (Rete dei Laboratori Universitari di Ingegneria Sismica) and the INGV (Istituto Nazionale di Geofisica e Vulcanologia) within the S4 Project funded by the Italian DPC (Dipartimento della Protezione Civile).
