mechanical properties of masonry compared to that of the ground floor. The nonlinear model showed a greater capacity to redistribute seismic actions, allowing it to significantly exceed the capacity of the first floor. On the other hand, the linear model provided more conservative results, suitable for simplified assessments. The failure modes provided by the analytical model were quite consistent with the mechanisms exhibited by the nonlinear static analyses carried out with 3DMacro. Finally, the parametric study allowed to investigate the influence of SFRM thickness in terms of global shear capacity as well as damage mechanisms. Future works will aim to investigate the influence of coating-to-foundation steel connections and of the knowledge level of the structure on the global seismic response. Moreover, nonlinear static analyses will be used to better estimate the behavior factor q based on the ratio αu/α1 calculated for each analysis.
