Continuous monitoring of bearing forces and displacements on the high coast suspension bridge
(English)Manuscript (preprint) (Other academic)
This paper presents results from the longitudinal girder displacement and bearing force monitoring on a highway suspension bridge located in Sweden. The monitoring programme was initiated in 2005 by the bridge owner after the discovery of unusual and intense wear in the Teflon layers of the bearings. The initial work focused mainly on a long term monitoring of the bearing forces in the northern abutment. After the first monitoring period of one year the monitoring system was enhanced with a traffic camera, a temperature sensor and accelerometers mounted on the two hangers closest to the instrumented bearing. The monitoring period presented in this paper covers ten months from February to December 2010 and focuses on the horizontal displacement of the girder and on the forces registered in the north-west bearing in conjunction with the traffic information provided by the traffic camera.
