Abstract

The author proposes the principal modal analysis by which the degrees of freedom can be drastically reduced, compared to conventional eigen modal analysis, while reproducing the dynamic response reasonably well.When this technique is applied to a phenomenon which has many modes, it is possible to catch a clearer mechanism than by using eigen mode analysis. Theory testing on a two degree of freedom model and case studying to a finite element model of real structure are introduced.
