State of the Art of Geodetic Bridge Monitoring

W. LIENHART, M. EHRHART

Abstract


To ensure the structural health of bridges and their compliance with normative regulations, e.g. Eurocodes, it is important to know their displacements and their vibration characteristics including natural frequencies and amplitudes. Until recently, geodetic sensors were not capable to measure bridge vibrations due to the low measurement rate of the sensors. This changed within the last years. We therefore compare different state-of-the-art techniques for geodetic bridge monitoring, including total stations, radar systems, image-based approaches and GNSS sensors.
