Abstract

An estimate method that used a parameter written C o is proposed in this paper. It's possible to estimate the damping performance by using the parameter C o between different size structures. Because the parameter C ois dimensionless, the size of the structure is irrelevant to estimate. The applicability of this method was proven to be high by using the observed data. In addition, this paper proposes a method to presume the parameter of the proportional damping equation considering the scale effect. And, the characteristics of the proposed equation and the relationship with C o were identified.
