Experimental determination of the load-bearing and deformation characteristics of the Flöhatal Bridge at Hetzdorf

The article describes the complex on-line measurement system with 87 measuring points for static measurements and 46 parallel measurement channels for the acquisition of dynamic signals.

Deck slabs in reinforced and prestressed concrete as used for railway bridges are being examined within the framework of an international research project. The measurement object in this article is the Flöhatal Bridge at Hetzdorf in Germany which was constructed as part of the project to straighten the railway line between Chemnitz and Dresden.

Strains in the concrete and on the transverse reinforcement were measured together with deformation in the box girder cross-section, wheel loads from locomotives and various temperatures.

The article describes the complex on-line measurement system with 87 measuring points for static measurements and 46 parallel measurement channels for the acquisition of dynamic signals. The main feature of the results is the comparison between the computed and measured results.
