Computational And Experimental Modeling Of Dynamic Foundation Interactions With Sand, Phd Thesis, Jeramy C. Ashlock
Jeramy C. Ashlock
The subject of dynamic soil-structure interaction (SSI) is fundamental to the design of structures and foundations to withstand dynamic events such as earthquakes, explosions and vibrations from traffic, wind, waves and machinery. With the tools of modern experimental and computational methods, a critical evaluation of current concepts and capabilities for the dynamic characterization of both surface foundations and embedded piles in granular soils is the first target. Well suited for this kind of fundamental study, a variety of scaled-model surface and pile foundations are designed and tested in a large geotechnical centrifuge using dynamic forced excitations. Used as a rigorous …

The mechanical properties of a cohesionless granular medium are strongly dependent on the confining stress, which varies three-dimensionally under a surface foundation due to gravitational and surface loading effects. Success in predicting a foundation’s response to dynamic loading is therefore highly dependent on the appropriate choice of material properties for a given theoretical model. Presented in this thesis are critical results from an investigation of dynamically loaded square foundations on granular soil using a geotechnical centrifuge. From the results, it is shown that the characterization of the vertical mode of vibration of the square foundations via the homogeneous half-space theory …
