The Salmbach Bridge (Fig. 4) is a slightly skew simply-supported
slab bridge with a width of 13 m spanning 7.5 m.
The bridge was built in 1993.
Some cracks in the transversal direction could be
observed on the underside of the deck slab, however, none of
the cracks could be observed to run the full width of the bridge.
The irregular distances between cracks indicated that the cracking
pattern was only partially developed.
The Arndorfbach Bridge (Fig. 5) is a 3-span slab bridge with a
span arrangement of 6.3 + 12.6 + 6.3 m. There are elastomeric
bearings at the abutments and hinged connections between piers
and the deck.
The bridge was built in 1967.
Some cracks in the transversal direction could be observed on the underside in the
middle of bridge.
Again, the crack pattern was only partially
developed.
During close inspection of this bridge it could be
observed that there are a few more cracks under the lane in the
Weiz–Gleisdorf (W–G) direction.
