Descripción
Laminated glass plates are sandwich elements in which glass layers present a linear elastic behavior whereas the interlayer (i.e. polivinyl butiral: PVB) is considered linear viscoelastic. In operational modal analysis, mass normalized mode shapes cannot be directly obtained, i.e., the mode shapes identified from the spectral densities are arbitrary normalized. In the last years, several methods have been proposed to scale mode shapes, such as the mass change method. This method consists of repeating modal testing after changing the mass at different points of the structure where the mode shapes are known. In this paper, the scaling factors of a square laminated glass plate, supported at the corners, have been estimated combining operational modal analysis and the mass change method. In the experiments different mass configurations were used in the scaling factors estimation. The experimental results are compared with those predicted by a finite element model.
