Method for the determination of the modal parameters of a structure both in the construction and exploitation phase, which comprises the steps of: - install and configure a position measurement equipment in the structure; - obtain a set of observations with the positioning measurement equipment: 2n 1 positionings in a point of the structure and in at least one of the three spatial coordinates, n being an integer and greater or same as 7; - given the 2n 1 positionings, select the coordinate or coordinates on which you want to perform the analysis; - obtain the block of observations of positions; - from the block of observations of positions, obtain the block of displacement observations; - for each displacement value of the displacement observation block, apply the fourier transform; - extract the modal parameters of interest; - compare the results obtained with those calculated theoretically by the designer.

Metodología para la determinación de los parámetros modales en estructuras que se encuentran en fase de construcción o de explotación. La importancia del conocimiento en tiempo real de los parámetros modales de una estructura ya sea en su fase constructiva como en fase de explotación da un importante y fundamental valor añadido a la calidad global de construcción de la estructura, así como su estado real durante su vida útil, adquiriendo este aspecto más interés y relevancia si se puede realizar exclusivamente a partir de observación de posicionamientos con sistemas de posicionamiento global como pueda ser GPS.
