Descripción
It is well known that mode shapes cannot be mass normalized when operational modal analysis (OMA) is used to estimate the modal parameters. In the last few years, some equations have been proposed by different authors to scale mode shapes using the masschange method. Some of the proposed equations are approximate because the change of the mode shapes of the modified structure is not properly taken into account whereas other equations can be considered exact because they are derived from the theory of structural modification. In this paper, the scaling factors of a symmetric scale model of a two story building, presenting repeated modes, have been determined by the mass change method. The results are compared with those predicted by a finite element model set up using the commercial FEA software ANSYS. The floors have been modelled using shell elements whereas 2 node beam elements have been chosen for the columns.
