Abstract
This paper deals with the evaluation of the seismic resistance of a reinforced
concrete building after a seismic retrofitting that includes both a partial
reinforcement of the existing structure and a base isolation system. The seismic
performance of the building has been evaluated with reference to the collapse
conditions. To this aim three-dimensional nonlinear static analyses have been
performed and a procedure for the definition of simplified two-degrees-offreedom
nonlinear systems, equivalent to the base isolated building, has been
assessed. The equivalent simplified systems allowed to perform a wide number
of nonlinear dynamical analyses with reference to several seismic inputs. The
ultimate capacity of the retrofitted building has been conventionally
