| Abstract: | In this paper a complex mode synthesis method for structural system with hysteresis damping is presented. The method is based on Craig mode synthesis method of components with fixed interface. The calculated examples have shown that the method gives much better accuracy not only on frequency but on the mode shape. The further reduction of the synthesis degree of freedom is also discussed. |
