*4.1. Bridge Description*

The bridge studied is a single span prestressed concrete precast bridge of 40 m. The section of the bridge is formed by two prestressed concrete precast isostatic beams with a U-shaped cross-section. The cross-section integrates a 12 m upper reinforced concrete slab. Note that the substructure is not included in the analysis since it depends on the ground characteristics and the orography. Figure 1 shows a general view of the bridge. The bridge is located in the eastern coastal area of Spain and the environmental ambient corresponds to XC-4 according to EN 206-1 [24]. Thus, corrosion is mainly caused by carbonation.
