Llobregat River’s last bridge (placed in El Prat de Llobregat, Barcelona) is in construction. The bridge will be a landmark in the area, the total length is 304 m, the main span is 150 m and deck is 29 m wide. But the singular point is the structural scheme, a complex combination of frame and half-through arch.
During the construction process the structural scheme changes several times, this evolutionary process establish the final forces and stresses in the bridge, in other words, the construction is bonded to the final result. In order to verify all the construction phases the structure has been monitored in real time. The instrumentation combined with the usual control allows us to evaluate the structure stress state and compare with the models, as well as verify the correct building or adjust the process in next phases.
