“…The resulting damage distribution is illustrated in Figure 7b in comparison to the one obtained in the case with slabs, showing higher number of involved walls, evidencing the necessity of an adequate modelling of the floors and their influence in the seismic response of the structure In Figure 8, the damage distributions obtained from the model with large mesh division and the model with refined mesh division are reported, as an example, for the Eastern walls of the building. The comparison showed that the refined model is able to provide a very precise cracking distribution and a higher damage level, mainly due to the advantage of having a division higher than one in the direction of the wall's thickness, but with a sensibly higher computational cost [19]. For the first three modes, Figure 9 shows the variation of the periods' values for the two mesh divisions due to the damage progression during the non-linear analysis.…”

This paper presents the results of the investigation on the seismic behaviour of an important historical masonry building, the "Ancien Hôpital de Sion". The building is sited in the city of Sion, capital of the Canton of Valais, characterized by the highest seismic hazard in Switzerland. The complexity of the structure poses challenging questions in the evaluation of its behaviour, requiring the use of different assessment techniques. A detailed three-dimensional model of the building was developed through the applied element method (AEM), accounting for all possible failure mechanisms occurring in a masonry structure. The analysis of damage distributions allowed to identify the most vulnerable areas of the building and to obtain indications on the necessity of seismic strengthening. The effects of the level of connection offered by the timber floors was also investigated. The kinematic limit analysis was employed for the evaluation of the building's capacity through possible overturning of the most vulnerable portions of masonry. The collapse mechanisms analysis was performed with both linear and non-linear approaches applying the capacity spectrum method. The numerical and the analytical results were finally compared in order to evidence the applicability of the procedure for the assessment of historical buildings.

“…The size of the meshing was selected to avoid creating elements with large aspect ratios and was opportunely validated [19]. The model of the building is reported in Figure 5a, where the timber beams of the floors can be seen.…”
