Samenvatting

The current research and design thesis deals with implementation of a 30-meter-long bridge with a cross section made with an innovative hybrid material composed of GFRP composite and steel members. A preliminary design consisting of analytical calculations creates a reference line on top of which FEM modelling is added with the purpose of investigating potentially critical effects that can render the structure unusable. These effects include buckling of composite webs under wheel loads, thermal stresses due to temperature variation over the lifespan of the bridge and stresses in the resin layer binding the composite to the steel member. After producing and interpreting the results, a conclusion summarizes the content and states whether such a bridge can be implemented. Finally, several requirements suggest further research possibilities that can help to offer a complete picture regarding the structural behavior of this material in a bridge deck.
