Abstract
The results of an extensive experimental study of the dynamic interaction between the foundation block for the NEES/UCSD Large High Performance Outdoor Shake Table and the surrounding soil are presented. The vibrations induced by the two large NEES/UCLA eccentric mass shakers were recorded at multiple stations within the reinforced concrete foundation block and on the soil up to distances of 270 m from the block. The results obtained for the deformation pattern of the reaction block, the frequency response at selected stations on the block, and the average rigid-body motion of the foundation and its dependence on frequency for longitudinal (EW) excitation are presented in detail. Comparison of the response during shaker-induced vibrations with that resulting from the much stronger actuator forces shows that linearity holds for the range of forces involved. The attenuation of the ground motion away from the reaction block is also described.
