摘要: A shallow elastic arch subjected to a static load is considered. Plots of magnitude versus the squares vibration frequencies (i.e., characteristic curves) have been obtained previously. Here, effects initial thrust and foundation on curves are investigated. For simplicity, results derived for an with pinned ends sinusoidal shape, assumed distribution.
