The possibilities of Hybrid steel-FRP bridges in movable highway spans

The increasing number of vehicles does not stop, axle loads get higher and wheel contact surfaces have decreased causing bridges to show significant fatigue damage. Demolishing and building a new bridge is out of the picture due to the current ideas on sustainability and environmental impact. Therefore renovation is necessary, as much of the...

Parametric design of steel orthotropic bridge decks for fatigue calculations

Currently the transport & planning (transport & logistics) group from Royal HaskoningDHV makes their pre-design for steel orthotropic bridge decks by using rules of thumb and experience. In the final design-stage this is verified whereby the force distribution is checked with the help of 3D finite element software (FEM). In this stage...
