Response of Tension Piles to Vertical Seismic Motion in Saturated Fine Sand

摘要

This study addresses the problem of vertical dynamic response of axially loaded piles with tension bias under the vertical component of earthquake loading. Of special concern are (a) whether the pile loses capacity during the period of strong ground motion and thereby either fails or operated under a lower-than-desirable factor of safety, and (b) if the pile loses capacity, whether that loss is permanent or whether it is regained after the conclusion or seismic event.
