Abstract

In the present research, is proposed a new methodology for estimating tension forces in cables on the basis of their modes and natural frequencies of vibration, by developing a computer application leaning on the finite element method (FEM) and a detailed analysis of signals. In this paper is presented a state of the art with some of the work done around the world, a conceptual framework and a proposed methodology for its development and implementation. The computer application which was programmed in MATLAB ®, which was validated through experimental measurements on a scaled prototype and some cables of a cable stayed bridge under construction in Colombia, allows to estimate the magnitude of the cable’s tension with minimal errors.
