| | Integral abutment bridges are becoming popular in Europe, mainly due to
long term reduced maintenance costs. The lack of bearings and expansion joints means
that the consumables are eliminated ensuring a longer life span of the structure and
minimizing the need of human intervention.
Most integral bridges usually have small or middle lengths, but in the last years longer
bridges are being built. Special attention should be given to the soil-abutment
interaction, as the bridge lengthens and shortens during the day and during the year,
due to temperature differences and loading. Therefore the soil structure should
accommodate the cyclic movements of the abutment and avoid settlements and cracks.
Transition slabs are also key elements and targeted design can improve the behavior of
the bridge.
In the past years several integral bridges were built in Romania. The paper presents
examples with bridges from the Romanian Motorway system, addressing the specific
needs and adopted solutions in regard to their lengths. |
