摘要

Fastenings to concrete can be subjected to complex loading situations. The resistance of the connection under the combined action of shear, bending moment and normal force depends strongly on the failure mode of the connection. In order to investigate the resistance of dowel connections under combined actions, a special test set-up has been developed which allows to submit a dowel connection to complex loading conditions. A case study was made for a connection element of a light-weight pedestrian bridge, composed of a concrete deck with a truss substructure. The truss is composed of sandwich panels, consisting of glass fibre reinforced IPC skins (Inorganic Phosphate Cement, a non-alkaline inorganic resin developed at the Vrije Universiteit Brussel) separated by a polystyrene core. The dowel connection is needed for the connection between the concrete deck and the sandwich diagonal members of the truss. Connection elements with different dowel diameters and different spacings between the dowels are tested.
