The dynamical properties of a laminated glass are investigated by applying the Fitting Time History (FTH) method to experimental free vibration response. Both linear and the nonlinear parameters are detected, and attention is focused on these latters since they are the most important element of novelty of this work. Some one-mode identifications are considered first, and then the approximation is improved by considering multi-mode identifications, that allow us to detect simultaneously the linear and nonlinear properties of various vibration modes, a fact that is an appealing feature of the FTH method.

Abstract
The dynamical properties of a laminated glass are investigated by applying the Fitting Time History (FTH) method to experimental free vibration response. Both linear and the nonlinear parameters are detected, and attention is focused on these latters since they are the most important element of novelty of this work. Some one-mode identifications are considered first, and then the approximation is improved by considering multi-mode identifications, that allow us to detect simultaneously the linear and nonlinear properties of various vibration modes, a fact that is an appealing feature of the FTH method.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
