Abstract The preliminary experimental results from the tests on a 4-storey R/C frame structure are presented and discussed. The full-scale model is representative of the common practice of 40-50 years ago in most southern European countries. Special attention is devoted to the study of a retrofitting solution based on bracing and rubber dissipaters, which is intended to increase stiffness and damping and consequently reduce the earthquake deformation demands. Keywords: Dissipating devices, earthquake tests, global modelling, reinforced concrete buildings, seismic retrofitting.
