โœฆ Synopsis

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

The free vibrations of a transversely isotropic prestressed linear elastic half-space, localized close to a free surface, are considered. The free vibrations of a prestressed transversely isotropic infinite plate, lying on an elastic foundation, are also considered. The dispersion equation is analys

The resonance frequencies of the 250-m-high arch dam of Mauvoisin are obtained by way of ambient vibration tests. It is observed that the resonance frequencies initially increase with rising water level and then decrease with a further rise. This is linked to the two competing features of increasing
