The Rába-Bridge at Rábahídvég on trunk road
No.8 was built in 1948 and reconstructed in 1995.
The main girders are tied R.C. arches with rigid
steel reinforcement, the deck is a R.C. plate
supported by cross- and longitudinal girders. The
hangers have been replaced for Dywidag bars. The
main aim of the reconstruction was to increase the
load bearing capacity of the bridge from the
original 20 to up to 80 to. The strenghtening of the
deck required the R.C. mantling of the longitudinal
girders and the crossgirder ends, an additional
concrete layer of 6 cm thickness on top of the deck
and the external prestressing of the cross girders.
In order to reach the required „A” class load
bearing capacity, the longitudinal external
prestressing of the deck and the injection of the
steel tubes inside the R.C. arches was also
necessary. |
