Advances in Ambient Vibration Testing: Ganter Bridge, Switzerland

Recent developments in experimental structural dynamics and Finite Element model updating based on experimental results are briefly described. With state-of-the-art hardware and software, it is now possible to completely process large amounts of ambient data from 16 or more channels immediately on site. The main part of the paper presents an Ambient Vibration Test recently performed on the Ganter Bridge in Switzerland to establish the performance of this system. The test set-up, data acquisition, data processing methods and test results are described.
