Seismic Analysis and Rehabilitation by Steel Jacketing of a Historical Precast RC Industrial Building
The field of seismic upgrading and retrofitting of historical buildings is an ever-developing discipline. The need of updated and ameliorative intervention techniques is fundamental, especially in highly seismic regions as Italy. The advantages of steel for the application of these techniques have been clearly stated. Nevertheless, its use as structural material is still limited both for new constructions and retrofitting of existing ones. The current study takes the inspiration from these premises, focusing the interest on the application of local steel interventions for rehabilitation of a historical precast RC industrial warehouse, that was struck by the Emilia-Romagna seismic sequence occurred in 2012. Two different local jacketing interventions of columns have been foreseen. Moreover, the efficiency of different beam-to-column joint types, namely hinge, semi-rigid and rigid joints, as well as the presence of a roof rigid diaphragm, have been examined and compared to each other by static non-linear analyses. Finally, from the achieved numerical analysis results it has been shown that the proposed local interventions also provide the global retrofitting of the building.
