REXEL is a software, developed since 2005, for computer aided selection of spectrum matching real records sets to be used as an input for dynamic structural analysis. The tool, initially developed aiming at matching European standards, has been significantly enhanced recently, and now it is possible to define target spectra according to several international codes, and to select worldwide records from three different databases. Moreover, it is now possible to pre-select records based on ground motion intensity measures, alternatively to magnitude, distance, and epsilons. For Italian sites, REXEL now also allows to link the selected record set to the hazard at the site through the design earthquakes from disaggregation. Finally, implemented conditional hazard allows to account in selection for the cyclic content of ground motion in a probabilistically consistent manner with respect to the design acceleration. Major improvements implemented in REXEL 3.3 beta are shown in the paper.

Abstract
REXEL is a software, developed since 2005, for computer aided selection of spectrum matching real records sets to be used as an input for dynamic structural analysis. The tool, initially developed aiming at matching European standards, has been significantly enhanced recently, and now it is possible to define target spectra according to several international codes, and to select worldwide records from three different databases. Moreover, it is now possible to pre-select records based on ground motion intensity measures, alternatively to magnitude, distance, and epsilons. For Italian sites, REXEL now also allows to link the selected record set to the hazard at the site through the design earthquakes from disaggregation. Finally, implemented conditional hazard allows to account in selection for the cyclic content of ground motion in a probabilistically consistent manner with respect to the design acceleration. Major improvements implemented in REXEL 3.3 beta are shown in the paper.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
