| Abstract: | This paper's purpose is to calculate floor forced vibration by substituting direct superposition of Ritz vectors for subspace iteration, to raise operation speed and reduce storage space on minicomputer.This paper proposes a program to compute floor forced vibration by direct superposition of Ritz vectors. A concrete workshop is calculated with this program and the result is very good. |
