Seismic Analysis and Retrofitting by Steelwork of Existing Precast RC Buildings: A Case Study

The seismic retrofitting of existing buildings is still an open issue in the Seismic Engineering field. The need of upgrading and rehabilitation techniques is crucial, especially in highly seismic regions, such as Italy. In this framework, the advantages of steel have been clearly stated. However, its use as technology for seismic improvement and retrofitting of constructions is still limited. This study, focused on an industrial precast RC warehouse struck by the 2012 Northern Italy earthquakes, has the aim of both discussing improvements and disadvantages connected to different beam-column joint types and highlighting how local steel interventions can also improve the building global response.
