Abstract EN
The paper provides an overview of ambient vibration tests and numerical analysis performed in the framework of Project NATO SfP 983828.
The aim of the research is the definition of the dynamic characteristics of bridgeson the examples.
The paper considers three case studies: two older existing bridges and one newly constructed bridge.
A comparative analysis of natural frequencies and mode shapes, obtained by ambient vibration measurements (AVM) and mathematical models (AMs), was carried with the aim to demonstrate the usefulness of ambient vibration tests for identification of the modal parameters of the tested bridge structure.
Agreement between AVM and AMs results is very good.
The mode shapes are very similar.
Some differences between computed and measured frequencies were obtained, which can be attributed to the real nature of the boundary conditions, the uncertainty in the material properties of structure elements, and the mathematical modelsassumptions.
