In technical diagnostics of load-bearing tendons of bridge and building structures, vibration methods are popular due to simplicity, speed of results and low costs of their application. The aim of the research was to develop a method for measuring the load-bearing cables stress. The article presents the results of tests on the cable testing stand, which enable identification of the parameters of the cable dynamic model. In the research, a technique was applied consisting in impulse stimulation to vibrations of the tense steel cable and analysis of signals, which are a response of the cable to this excitation. Using the modal analysis method, the dependence of the frequency of various forms of the cable natural vibrations on the cable tensioning force was determined. Three types of cables were tested. The bending rigidity of the cable was determined. Using the modal analysis method as a reference method, the usefulness of a simpler method of evaluating cable natural frequency, was examined.
