Bridge over the motorway A27, steel truss with a FRP deck

摘要

In the Netherlands a bridge is built crossing the motorway A27 near Utrecht. This bridge wasrnconstructed as a combination of steel and FRP, with a total length of 140 meters. The bridge isrnmade of a steel truss girder and a deck of FRP (composite).The connection of the composite deckrnto the steel truss girder was a challenging part. To solve this problem two load-paths arernintroduced. The first is made with an adhesive compound, the second with a pin-hole connection.rnAlso the location of the bridge with the foundation inside a polder construction with highlyrncompressible soil was a challenge to solve. The use of a jet grouting was necessary to solve thisrnproblem.
