Abstract
The paper summarizes an example of assessment of a cable-stayed pedestrian and motorway overpass in Tuzla city urban environment based on static and dynamic tests. The outlined research included testing of bridges induced by vehicles, ambient vibration testing, modal identification, finite element modelling and assessment of structural behaviour. The field investigations involved measurement of deformations (displacement and dilatation), vibrations induced by vehicles and ambient vibrations. Modes were identified by using Enhanced Frequency Domain Decomposition techniques (frequency domain). Details on the experimental procedures, instrumentation and data analysis techniques are presented and discussed. In the numerical study, deformations forms and vibration modes were determined using a 3D finite element model of the bridge and the information obtained from the field tests. Some conclusions and recommendations for similar bridges were given at the end of the paper.
