ABSTRACT
Before 1950 steel-concrete bridges are built without a dowel connection between the steel and concrete part of the bridge deck. The steel part of this bridge type is a common steel I-type girder. The concrete part has no bearing capacity reinforcement. The span length vary from 5-15 meter. The assessment of those structures aren’t covered by the Eurocode, a dowel connection between the steel and concrete part is missing. Slip behaviour of the bonded connection between steel and concrete is unknown. In-situ cycle loading tests, ULS cycle and ULS lab tests with Eurocode TS load configurations are executed on 5 samples, constructed in 1938. They show the bonded behaviour. Solid3D FE model simulations confirm the test measurements. This process leads to a practical engineering re-examination assessment protocol based on a simple Shell2.5D FE model. The historical view of the city of Amsterdam can be saved and reduces the renovation costs.
