In order to guarantee the serviceability of communications, it is required that the guyed mast present a maintenance plan that allows the evaluation of different relevant aspects for their adequate structural performance, among which it is important to control the working tension at which the guys are located. For this, the planned techniques correspond to the direct and indirect methods. Both have advantages and disadvantages. The direct, precision in measurement but little available equipment, the indirect, simplicity in execution but imprecision in the results. As an alternative to the above, in the present investigation it is proposed to infer the tensional state of reins from the measurement of their natural frequencies using the technique known as Ambient Vibration Measurements (AVM), and then using the vibration theory of cables, infer the tension in them. In the present work, this technique was applied to the reins of an existing guyed mast. The stresses inferred in this way were then compared with measurements carried out by the direct method, as well as with results obtained from numerical modeling.
