Afterwards, in this study also the influence of the structural configuration on the ideal case global response is investigated. To this aim, as previously introduced, four different configurations are considered, indicated as Model 1, Model 2, Model 3 and Model 4, and illustrated in Figure 6. Again, 7 TH analyses are carried out along the in-plan directions X and Y, by assigning the same spectrum-compatible accelerograms considered for the previous investigations (Figure 4). In this case, the Connection A is considered only.
