1.3. Data post-processing From the monitoring strategy, the gathered data is divided into two subcategories, pre-retrofitting (Dataset 1 in Figure 4a and Figure 4b) and post-retrofitting (Dataset 2, in Figure 4c and Figure 4d). The acquisition of this database is known as raw data, the main features acquired for further analysis are the displacements and the temperature, as depicted in Figure 4a to Figure 4d.

a) Crack meter displacement of North Pile 1 – Pre-Retrofitted

b) Crack meter displacement of North Pile 2 – Pre-Retrofitted

c) Crack meter displacement of North Pile 1 – Post-Retrofitted

d) Crack meter displacement of North Pile 2 – Post-Retrofitted

The data is then cleansed to detect outliers that may otherwise mislead the study. In all datasets regarding the displacement’s measures, a statistical approach is adopted, and for the temperature datasets a moving mean with a
