Abstract
This paper elaborates the procedures for scaling prototype structure to
scale model according to similitude laws keeping the dynamic properties of the original
structure. The scaling procedures are very suitable for experiments where the purpose
is not only to check the strength of the structure, but also to investigate the
performance of other dynamic devices mounted on the primary structure such as
dynamic absorbers. In such cases, the use of condensation methods comes to mind in
order to reduce the original d.o.f. and make the model structure behave same in the
first several modes as the original structure.
