| Abstrakt: |
The determination of tension in bridge cables by means of vibration measurements has been used by the Direction of civil engineering expertise for decades to monitor the bridges managed by the Walloon Region (SPW). Over time, it has appeared that the traditional methodology, based on sparse on-site measurement and the taut string theory, suffers from certain limitations: the two most important are the delay between measurements (at best once a year) and the difficulties in solving the equation linking the vibration response to the tension in the stay, in the case of short or geometrically complex cable. An agreement was concluded between the SPW, the University of Liège and V2i, a company specialised in vibrations, to develop a solution including a software allowing the tension determination in any kind of bridge cable and the hardware to monitor the cable tension remotely for a long time. |
