REXELweb: a tool for selection of ground-motion records from the Engineering Strong Motion database (ESM)

Abstract

This paper illustrates REXELweb, an updated online version of REXEL, which is a tool for the automatic selection and scaling of spectrum-compatible ground- motions for dynamic analysis of structures. REXELweb allows to define target spectra according to user-definition or design provisions (Eurocode 8 and Italian building code), as well as to uniform hazard spectra (UHS) based on a European hazard model. REXELweb implements all functionalities and options of REXEL through web-services that are accessible either via a MATHWORKS-MATLAB script or a user-friendly web-interface. The program selects records from the Engineering Strong Motion database (ESM), which is a daily-updated Pan-European repository of high-quality ground-motion records. These features make REXELweb a potentially useful tool for researchers and practitioners.
