### Ambient Vibration Results for 2024  
Based on the analysis of the previously obtained results, the 2024 ambient vibration study once again focuses on the frequency range around 2.5 Hz, which was identified as relevant to the structural dynamics. Using a band-pass filter applied to the original data sampled at 400 Hz, the two frequencies with the highest participation per analysis were identified, considering only those with a participation factor greater than 10% and maintaining the same tolerance for the dynamic parameters as in the previous results. Figure 11: Boxplots of orders grouped by a frequency threshold of 2.5 Hz for 2022–2023 ambient vibration. (**a**) Orders with frequencies greater than 2.5 Hz. (**b**) Orders with frequencies less than 2.5 Hz. Figure 12 shows the results of the 2024 ambient vibration data, focusing on the frequency around 2.5 Hz. This analysis centers on identifying the dominant frequencies and their participation in the range of interests, using data collected from four synchronized sensors. Continuing with the analysis, the clustering process is applied to the data to identify frequency boundaries. In Figure 13, it can be observed how the frequencies are grouped into different categories. Consistent with the previously analyzed data, red points represent the frequency boundaries identified for each model order, enabling the observation of dominant frequency ranges and their variations as the model order increases. When comparing the clustering results between the periods of 2022-2023 and 2024, a similar trend is observed in the stability and grouping of frequencies as the model order increases. In both analyses, the dominant frequencies in the range close to 2.5 Hz show consistency in their identification, standing out as significant modes across different orders. As the model order increases, the frequencies tend to group coherently, and the frequency boundaries, indicated in red, maintain similar values in both periods, reflecting possible stable patterns in the structural dynamics. To analyze the concentration of data by order, boxplots were constructed while maintaining the 2.5 Hz threshold. Figure 14 presents these charts, allowing a visualization of the dispersion and variability of frequencies in each order, with frequencies above 2.5 Hz shown at the top and frequencies below 2.5 Hz at the bottom. Figure 12: Identified frequencies in the X direction per order for data filtered at 2.5 Hz for 2024 ambient vibration (only frequencies with >10% participation are shown). It can be observed that for frequencies above 2.5 Hz, there is a greater dispersion compared to frequencies below this threshold, suggesting the existence of additional frequency thresholds.

In contrast, frequencies below 2.5 Hz show a more uniform dispersion, which could indicate that modes in this region are more stable or less susceptible to dynamic interactions. The presence of numerous outliers in both subsets highlights the existence of frequencies that deviate significantly from the average behavior. For frequencies above 2.5 Hz, the outliers are more dispersed and observed across a larger number of orders, reinforcing the hypothesis that the modes in this region are more sensitive to external factors or model complexity. In the case of frequencies below 2.5 Hz, the outliers are less dispersed and exhibit greater uniformity, suggesting a lesser deviation of modes from their central behavior. As the model order increases, especially for frequencies above 2.5 Hz, the boxplots show a tendency toward greater dispersion.
