Historic iron and steel bridge bearings
history and options of preservation
We can observe a growing demand for the refurbishment or the retrofitting of the load bearing structures in numerous historic bridges. Thus their bearings made from either cast iron or steel are finally re-entering the focus of the structural engineers. But fundamental knowledge for an structural assessment of the historic bearings hardly exist - neither a proper method for an in-situ inspection of the bearings, nor reliable approaches to proof limit states, as for instance the serviceability. This lack of knowledge is very often the reason for the expensive replacement of apparently sound existing historic bearings.
The absence of reliable data for the structural assessment of these core-elements formed the trigger for the research project. Since 2004, in a first step the historical background for the development of bridge bearings has been researched and analysed. A referring dissertation thesis was submitted in May 2010.
Mainly based on this thesis, in a second step reliable methods to assess the historic bearings will be developed.
