[en] In order to remotely monitor tension in a cable over time, an appropriate method is based on the natural frequencies of the cable measured by means of wireless accelerometers. In this paper, an existing method is extended to determine the tension in long or short shallow cables with small bending stiffness and arbitrary end conditions. First, a low-order analytical model is developed to compute the dynamic response of a given cable. Then, the unknown parameters such as the end conditions, the exact length of the cable and the tension in the cable are adjusted, using an iterative nonlinear least-square algorithm, until the computed natural frequencies and associated mode shapes match the measured ones. This procedure is finally validated with field measurements collected on long and short cables.
