Abstract
The Severn Suspension Bridge carries the M48 motorway between England and Wales, it has an overall length of 1,600 m and has a main span length of just short of 988m. In 2010, a series of field tests were carried out by the authors, whereby 9 dual frequency GNSS receivers were placed on the Bridge and data gathered at rates of 10Hz and 20Hz over a 3 day period. Four GNSS receivers were places on top of the two pairs of support towers, and a further 5 placed directly onto the support cables at pre-defined locations.
Various data processing techniques, and filtering were used. The results showed various outcomes, one of which was the synchronization of the movements of the 136m tall towers with the suspension cables themselves.
This paper outlines the tests themselves, as well as the results, illustrating the magnitudes of the movements of the various locations, in addition to the frequency of the movements. The synchronized frequencies of the movements are also discussed.
