| 摘要： | This article presents an approximate method for the complex eigensolution of nonclassically damped linear systems representing a structure equipped with a passive damping device. The proposed algorithm does not require the standard state-space formulation and is computationally efficient compared to the existing methods. The complex eigenvalues are determined using an approximate solution of the characteristic equation based on a combination of perturbation and incremental approaches. The complex eigenmodes are subsequently calculated with the use of the obtained eigenvalues from eigenvectors of a significantly reduced eigenproblem defined in modal coordinates. The accuracy of the proposed method is demonstrated through numerical studies on a television tower. |
