| Abstract: | This paper presents a method to eliminate the effects of additive masses, stiffnesses and dampings on the complex modal parameters in experimental modal analysis. At the same time, in order to make the method adjust to vibration reanalysis of structural modification the method is developed. The results of the example show the method is available. |
