In this research the study of an experimental reduced scale stell model of a medium-rise building structure is presented. The model was dynamically protected with energy dissipators installed on rigidization diagonals. These devices are passive control elements able to reduce the earthquake forces in buildings. The energy dissipators utilized in the experimental tests principally involve the steel-steel friction to dissipate energy and to lower the seismic response. When the structure undergoes interstory drifts the devices dissipate energy increasing the damping of the structure.
