Abstract

A Global Navigation Satellite System (GNSS) has been deployed on the Lysefjord Bridge in Norway, to measure the static and dynamic displacement of the deck. One objective is to evaluate the systems capability to monitor accurately wind-induced vibrations in high-latitudes and mountainous terrain. GNSS measurements are compared to displacement records obtained from accelerometers located inside the bridge deck. For data of 10 minutes duration, the accelerometers were observed to monitor frequencies below 0.1 Hz with relatively poor accuracy. The GNSS measurements agreed well with the theoretical estimates of the quasi-static and resonant response of the bridge at low frequencies. The completion of the Galileo system in 2020 should expand the applicability and reliability of such systems for structural monitoring purposes in Northern Europe.
