ABSTRACT: The seismic behavior
of base isolated structures with friction pendulum slide bearings devices subjected
to near fault events characterized by significant vertical ground motion
components is investigated. In particular, in order to evaluate the effects of
vertical components on seismic response, non-linear dynamic analysis, carried
out by using several numerical models, have been performed by considering two
near-fault seismic events, L’Aquila 2009 and Emilia Romagna 2012. The obtained
results show that increasing vertical seismic motion base shear significantly
increases while relative displacements increase very little.
