Efficient approximate eigensolution for structures equipped with a passive damping device
Original language description
The technical note presents an approximate method for the complex eigensolution of non-classically 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 e cient 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 signi cantly reduced eigenproblem de fined in modal coordinates. The accuracy of the proposed method is demonstrated through numerical studies on a TV tower.
