“…The variety of different scenarios applied to the structure is the main reason that induced several researchers to investigate its dynamical behavior. [61][62][63][64] Figure 2(a) shows the structure's layout, where aluminum plates and four aluminum columns were assembled using bolted joints to compose each floor. Figure 2(b) shows the damage mechanism located at the center of the structure's top floor.…”

“…This distinction is particularly evidenced by the fluctuation in the values between each condition, especially for II, where the first term (ϕ 1 ) is less stable across the windows presented (characterizing the irregular pattern of II compared to a more regular PIS activity [39]). This characteristic is specific to this type of modeling and has been used in pattern recognition approaches involving, for instance, structural health monitoring [47][48][49][50] as well as analysis and validation of computational models in describing II and PIS activities [39], since the AR coefficients are sensitive to changes in the signal dynamics [48].…”

Moreover, within each condition, the coefficients are relatively bounded over the time windows (for further results, please see Fig B in S1 Appendix), which suggests that not only the patterns of II/PIS are sustained differently, but also that the coefficients do reflect this consistency.…”
