Description:
This paper introduces REXELite, an internet version of REXEL, a software
for automatic selection of ground motion suites for nonlinear dynamic analysis of structures.
REXELite was developed with the aim of integrating an advanced earthquake records’
repository, such as the ITalianACcelerometricArchive (ITACA), with a tool to define seismic
input for engineering seismic analysis according to international standards (with priority to
Europe). In fact, REXELite allows to define target design spectra according either to Eurocode
8 or to the Italian building code, and to search ITACA for suitable sets of seven records
(comprised of one or two horizontal ground motion components) matching such target spectra:
on average, in a user-specified period range, and with the desired tolerance. The records in
the set also have, individually and according to some criteria, the most similar spectral shape
with respect to that of the code. Selection options include magnitude, source-to-site distance,
soil conditions and, if desired, linear scaling of records to reduce further record-to-record
variability of the selected suite.This paper introduces REXELite, an internet version of REXEL, a software
