✦ Synopsis

An extension of the field of applications of classical modal reanalysis procedures is described, for the case when the number of degrees of freedom of a modified structure is greater than that of the initial structure. This feature is not developed classically, and such a case is usually resolved by the use of modal synthesis methods. A pure modal reanalysis procedure, with all the theoretical developments, is presented here. It is shown that any classical reanalysis algorithm can be used as the basis of the method. A characteristic example is presented, and modal results are discussed and compared with those of a classical reanalysis procedure.
