Field Teams: Finale Emilia Viaduct
Date: 22/05/2012 Category: Viaduct Typology: R.C. / Prestressed R.C. Municipality: Finale Emilia Distance from epicenter: 10 km Damage Typology Transversal slip of the deck with partial loss of the support and damage to joints. Figure 1. Viaduct in Finale Emilia. Figure 2. Damage to joints. Figure 3. Partial loss of the […]
Field Teams: bridge at San Felice sul Panaro
Date: 29-05-2012 Category: Bridge Typology: R.C. Municipality: San Felice sul Panaro Distance from epicenter: 9 km Damage Typology Transverse dislocation of some spans (approximately 27 cm). The action of the seismic sequence along the longitudinal axis of the deck induced the mutual pounding of deck beams, as well as residual displacements (up to 20 cm). […]
Field Teams: bridge at Bomporto
Date: 29-05-2012 Category: Bridge Typology: R.C. Municipality: Bomporto Distance from epicenter: approx. 25 km Damage Typology Previous damage.

Field Teams: bridge at San Benedetto Po
Date: 29-05-2012 Category: Bridge Typology: R.C. Municipality: San Benedetto Po Distance from epicenter: 30 km Damage Typology Previous damage (concrete cover ejection) and evident subsidence of the spans.

Field Teams: Finale Emilia Viaduct 29-05-2012
Date: 29-05-2012 Category: Bridge 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 […]
