Abstract

The Reissner-Sung elastic half-space theory has often been considered and utilized for the design and analysis of the behavior of foundations subjected to vibrations. Findings from laboratory tests performed on a model footing resting on sand were used to arrive at the degree of validity and applicability of the theory. This investigation includes the determination of the magnitudes and phase relationships of the dynamic contact pressures at various locations across the bottom surface of a relatively rigid footing as well as its force-displacement characteristics. Five different mass ratios were used. By means of the displacement functions, the experimental results are shown to be compatible.
