Seismic Effects on Structures Supported on Piles Extending Through Deep Sensitive Clays
A general method of determining the dynamic response to seismic disturbances of structures when supported on long piles extending through deep sensitive clays is presented. This method accounts for the interaction effects between the superstructure and its pile foundations and the interaction effects between the pile foundations and their surrounding clay media. The method is applied to a specific bridge structure presently being designed by the California State Division of Highways which is to be erected at the Elkhorn Slough site. An extensive soil testing program was conducted using undisturbed clay samples taken from the Elkhorn Slough site; the results of this program are reported. The testing techniques used to determine the non-linear hysteretic stress-strain relations, the damping characteristics, and the creep characteristics of the clay are described in considerable detail. The dynamic response of the specific bridge-pile-clay system, when subjected to the N-S component of the 1940 El Centro ground acceleration, is presented in graphical form and its significance with respect to design questions is analyzed.
