The author describes a modification of Ritz method for finite element dynamic response analysis with large-scale stiffness matrix. In fact, one has to calculate Ritz vectors that approximate low eigenmodes. Simultaneously, the suggested technique leads to the reduction of requirements on disk storage space and to a fast problem solution.
