A utilização de vetores de Lanczos-Ritz na condensação dinâmica de estruturas

Abstract

The main objective of the dissertation is to analyse the condensation of degrees of freedom is Structural Dynamics. The Guyan reduction and the substructure representation by its Lanczos-Ritz vectors were implemented. A correction in the substructure base of transformation through an iterative process was proposed in order to obtain a correct modal representation of inertia forces.
