     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 was conducted in 2003. the vibrations induced by the two nees@ucla large eccentric mass shakers were recorded at multiple stations within the reinforced concrete foundation block and on the surface of the surrounding soil up to distances of 270 m from the block. the present paper focuses on analysis of the data recorded within the reaction block including the average rigid body motion of the foundation and its dependence on frequency, and the deformation of the block for longitudinal (ew), transverse (ns), and torsional excitation. comparison of the reaction block response during shaker induced vibrations with that for the much stronger actuator forces shows that linearity holds for the range of forces involved. comparisons with analytical results for a simplified model of the foundation show good agreement between experimental and theoretical results.
