The research project was undertaken to develop and test new composite bridge concepts that are easily buildable by the bestpossible application of construction materials and a high grade of prefabrication. One of the problems was the use of hybrid girders which lead to significant material cost savings and to a reduction of girder heights. Therefore the fatigue rules given in ENV3 Part 2have been validated experimentally and by numerical studies with a special regard to the local yielding of the web.

A further investigation were the use of dismountable shear connectors and headed studs with a diameter of 25 mm which are not considered in the codes until now. Studs with a diameter of 25 mm are favourable for bridges due to their higher shear resistance. This test series has included static and dynamic Push-Out tests.
Studies on the behaviour of joints of composite bridges took the special behaviour of partial and full prefabricated slabs into account. Reference bridges have been used to design the test set-up and cycle loadings were applied to simulate moving traffic loads. The investigations were performed in order to verify the opening of the joints, the fatigue behavior.
