The inelastic torsional response of an asymmetric-plan hospital building in Italy is studied. At this aim, a nonlinear analytical model is developed and verified using system identification based on environmental vibration tests. A non linear static procedure for the assessment of inelastic response of irregular buildings is proposed. This procedure accounts for mass distribution, higher modes contribution and mode-shapes correlation. Finally, the seismic assessment of inelastic torsional response is evaluated and the influence of eccentricity between mass centre and stiffness centre is investigated.

Abstract
The inelastic torsional response of an asymmetric-plan hospital building in Italy is studied. At this aim, a nonlinear analytical model is developed and verified using system identification based on environmental vibration tests. A non linear static procedure for the assessment of inelastic response of irregular buildings is proposed. This procedure accounts for mass distribution, higher modes contribution and mode-shapes correlation. Finally, the seismic assessment of inelastic torsional response is evaluated and the influence of eccentricity between mass centre and stiffness centre is investigated.File in questo prodotto:
