This approach, combined with the use of linear elastic spectra for evaluating the seismic demand, is now incorporated in current seismic provisions. However, rocking and elastic oscillators are very different and the current assessment procedures have the drawback of not considering properly the dynamic resilience of collapse mechanism and the scale effects occurring in the dynamic response. There is the definite need for an assessment method that takes into account the dynamic resources of the structure and the ability to dissipate energy through the rocking motion. This study aims at proposing a tool for the seismic assessment of historical masonry based on the selection of the local mechanism and the integration of the corresponding equation of motion under seismic inputs. Moreover, according to experimental evidences, the equation of motion includes a term related to an elastic Winkler-type foundation. Eventually, the dynamic analyses of a sample case study under seismic inputs is presented and compared with code-based approaches.
