In this paper a multi-level approach proposed by the Italian Guidelines on Cultural Heritage was adopted to assess the seismic safety of an unreinforced masonry building located in Naples (Italy).

Abstract

In this paper a multi-level approach proposed by the Italian Guidelines on Cultural Heritage was adopted to assess the seismic safety of an unreinforced masonry building located in Naples (Italy). In particular, the simplified model of the global seismic response at the territorial scale was used for the first level (LV1), while the nonlinear static (pushover) analysis and the equivalent frame modelling with nonlinear structural-elements were adopted for the more accurate global assessment level (LV3). Different evaluations of the safety indexes are compared in the framework of the LV1 level, with particular attention to their reliability in representing the main aspects of the seismic capacity of the building, in terms of the prevailing failure mechanism and the detection of the weaker direction. The achieved results were compared with those obtained by LV3 assessment level.
