SEISMIC REPONSE OF PILES TO OBLIQUELY INCIDENT SH, SV, AND P WAVES

The results are presented of a numerical study of the behavior of single piles subjected vertically and obliquely incident SH, SV, and P waves, in which soil-pile interaction effects are taken into account around the shaft interface as well as the pile base. For the soil domain, a new fundamental solution corresponding to a periodic dynamic point force in the interior of an elastic half-space, is implemented . The solution adopted for the free-field motions due to the seismic waves is obtained by direct integration of the differential equations of motion in terms of amplitudes. The methodology used takes into account the spatial variation in the distribution of seismic excitation, which leads to a more realistic modeling of the problem. Both the free-field displacement and stress components are used as the seismic input. The study results are presented in the form of nondimensional plots, and the pile-soil interaction is studied. This analysis procedure has also been extended to incorporate group effects.
