Development of an earthquake-resistant design of support and bracing structures of wooden bridges
In the past, seismic actions were often not considered in the design of timber and timber-concrete composite (HBV) bridges because wind and braking loads were assumed to dominate in the horizontal forces of the bridge. A preliminary study identified the need for seismic protection for these bridge types as well.
The aim of this research project is therefore to develop a concept with which conventional supports can be supplemented by a simple additional structure, which can also be retrofitted. For this purpose, U-shaped steel elements with high dissipation capacity are used. A series of tests on the interaction of these steel dampers and the bridge's elastomeric bearings will be used to validate numerical models.
