The seismic upgrade of an existing 5-storey reinforced concrete (RC) building through the use of friction-pendulum system (FPS) bearings is presented. The selected building is a model structure, representative of the buildings designed in the period 1960-1980 in Greece. The seismic assessment following the EC8-3 code provisions indicates the structural incapacity of the frame elements. For the seismic upgrade of the structure, FPS bearings are placed above the foundation level. A series of linear and non-linear analyses are performed and the results show that minimal interventions are required only at the ground floor level. The overall seismic performance and the limitations in the applicability of the proposed solution are discussed. It is concluded that seismic retrofitting through seismic isolation of existing buildings is a very good approach and should be widely used. |
