Structural health monitoring of the Gaertnerplatz bridge over the Fulda river in Kassel considering environmental conditions


Abstract eng:
The Structural Health Monitoring (SHM) concept for the bridge is characterized by the application of model parameter identification techniques utilized for relating experimentally observed changes of the modal data (natural frequencies and mode shapes) to the changes of the physical parameters of a Finite Element (FE) model. In the presented SHM application a systematic decrease of the natural frequencies with temperature was observed which could be described by a linear regression line for each frequency versus temperature. The differences between the test data and the data on the regression line exhibit a random distribution which was used for generating the statistical properties of the identified analytical model parameters. Results are reported from the SHM campaign which started shortly after the completion of the bridge construction in the year 2008 and which is still running up to today.
