A lot of the older German railway bridges are made of steel and have reached or exceeded the planed duration of use. Because it’s impossible to renew all these bridges at once, concepts for extension of duration of use without a decrease of safety are necessary. The paper shows the determination of load capacity of railway bridges using a combination of measurement and calculation procedures, that includes the detection of bearing reserves. Special procedures of short and long time measurements, which are contained in the standard of German Railway, will be explained. Based on a current project, the structural monitoring of a railway bridge in Chemnitz, the use of measurement procedures in combination with statically calculations is demonstrated. Particularly the concept for realistic determination of remaining life is explained and significant results are presented. |
