Serial Information: Journal of the Engineering Mechanics Division, 1956, Vol. 82, Issue 1, Pg. 1-9

Document Type: Journal Paper


Natural frequencies of continuous beam determined from difference equation formulation; these frequencies fall in periodically spaced groups separated by spectral gaps of widths; groups tend to uniform spectra as number of supports tends to infinity, but gaps remain giving band pass character to entire spectrum; wave propagation along infinite, periodically supported beam discussed.
