Abstract:
This paper presents the static and dynamic testing of the skewed overpass PS3. The static load test was performed with truck loads up to a total of 1268 kN. The vertical displacements were measured. The dynamic tests were carried out in three set-ups. 16 modes of the natural vibration of the structure were identified, using the technique of output-only modal identification, and the dynamic characteristics for each mode were estimated. For interpretation of the test results a finite element model for the bridge was built. The experimental results were compared with the analytical values computed by the FE model.
