The wear behaviour of arch bridge bearings

Structural bearings are connections between the substructure and superstructure of the bridge and may allow translations and rotations. They also transmit the external forces, acting on the superstructure, to the foundation. In the past years the traffic loads and intensity on the European traffic system has continuously increased. Bridge...

Mechanisch gedrag van brugopleggingen van de Dintelhavenbrug

New and current materials for bridge bearings are subjected to tests, according to the European Standards (NEN-EN 1337). With these tests the materials are not subjected to forces, displacements and rotations that are similar to those in practice. In order to give a critical opinion about the tests, it is necessary to obtain more knowledge about...

Traffic induced bearing loads and movements of a steel plate-girder bridge.

Structural bearings in bridges are subjected to loads and movements, causing wear of bearing components as PTFE-sheets, guides and internal seals. Nowadays, these components are tested for durability according to EN 1337. The parameters and procedures in these tests are questioned and, therefore, investigated in an existing plate-girder bridge...
