Effect of static interaction on vertical vibration of pile

An approximate numerical procedure to compute the vertical response of a ve rtical pile in a linearly elastic homogeneous sail medium in the time domai n is presented. The approach combines Novak's concept of energy dissipation through radiation damping and Poulos' concept of pile-soil-pile interactio n based on the Mindlin elastic solution. The predictions are assessed again st two experimental studies. This time domain approach has the potential to consider nonlinear soil behavior, discontinuity conditions at the pile-soi l interface, and pile-soil slip. The most significant promise of this schem e is to predict the propagation of vibration along the ground surface, gene rated from the vibration of the pile.
