| Abstract: | Through comparing and analysing the method of Ritz vector and Lanczos algorithm, which are used for computing natural vibration of structures, several theorems about the relations between the two methods are established in this paper. It is found, from the viewpoint of computation, the Lanczos algorithm is superior to the Ritz vector method. |
