The objective of this study is to evaluate the seismic performance of a base-isolated hospital building during earthquake strong ground motions. The case study is an existing RC building built in 80’s in the new hospital campus of Avellino and actually subjected to rehabilitation of structural members and seismic retrofit using base isolation. A nonlinear analytical model of the hospital building is developed and applied for the seismic performance assessment of the structure. As an alternative to direct integration, the non linear dynamic analysis is carried out with the Fast Nonlinear Analysis Method. Finally, both the possibility of poundings and inelastic torsional effects during strong ground motions were investigated.
