Abstract
The modal frequency response problem including non-proportional damping is solved with the recursive component mode synthesis (RCMS) method. For large-scale structures, the RCMS method is used not only for computing the eigensolution, but also for forming the modal frequency response problem. The efficiency and accuracy of this approach are verified with examples of structural Finite-element model compared with the conventional industry approach that uses the block Lanczos method.
