In the present paper the problem of determining the new modal parameters of a structure when subjected to additional constraints is considered. The aim is to avoid performing a new modal analysis when a structure is modified by adding constraints. The procedure, whose camputing efford is very low, is thouroughly explained for the determination of the new natural frequencies. The method can be applied to both numerically modelled structures and to data derived from experimental acquisition after the identification of the modal parameters is obtained.

Abstract
In the present paper the problem of determining the new modal parameters of a structure when subjected to additional constraints is considered. The aim is to avoid performing a new modal analysis when a structure is modified by adding constraints. The procedure, whose camputing efford is very low, is thouroughly explained for the determination of the new natural frequencies. The method can be applied to both numerically modelled structures and to data derived from experimental acquisition after the identification of the modal parameters is obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
