長方形基礎の加振による半無限粘弾性地盤の振動特性(その3)

Abstract

In this paper, we investigate the vibrational behaviors of a visco-elastic ground subjected torotational harmonic excitation on a rectangular surface area, by using the treatment described inthe preceding paper. The numerical results of the amplitude and phase characteristics of thedisplacement are shown graphically, along two principal a'ces of the rectangular area on the surfaceand along the depth below the center of the rectangular surface area. We diseuss the vibrationalcharacteristics for rotational eacitation, comparing with those for vertical and horizontal harmonicexcitations.
