The project has the purpose to inventorise, classify and evaluate existing methods for the long-term monitoring of bridge deflections. The result will be summarized in a report allowing a rational approach to the selection of measurement methods applicable to a given application.
Classical measurement methods (topometry, hydrostatic leveling) will be considered along with more recent developments, as for example methods based on inclinometers or optical fibers. The pros and cons of each method will be exposed in relationship with typical applications. Case studies of representative monitoring configurations will be included.
