This post presents some photos and observations from the Eucentre field teams when they visited a damaged viaduct in Finale Emilia.

Typology: R.C.
Municipality: Finale Emilia
Distance from epicenter: 10 km
Damage Typology
Transverse dislocation in some spans of the deck (approximately 20 cm); further transverse displacements could induce the complete loss of support for the beams of the deck which could directly lay on the top of the pier. The action of the seismic sequence along the longitudinal axis of the deck produced the mutual pounding of the beams, as well as slight residual displacements.
