Abstract
The conventional modal method in structural response analysis converges very slowly with respect to the number of natural modes. The convergent property is improved by using the condensed stiffness and mass matrices of the system. Thus, less natural modes are required and the difficulties of computing high natural modes are avoided. Undamped response due to deterministic and random excitations are discussed and numerical examples are given.
