Dynamic Full-Scale Testing Of A Pile Cap With Loose Silty Sand Backfill, Immanuel Kaleoonalani Runnels May 2007

Dynamic Full-Scale Testing Of A Pile Cap With Loose Silty Sand Backfill, Immanuel Kaleoonalani Runnels

Theses and Dissertations

Pile caps are used in foundation design to aid multiple single piles to act as a pile group to resist lateral forces that may cause overturning moments. The pile cap and pile group resist these forces by pile-soil-pile interaction, base and side friction along the pile cap-backfill interface, and passive earth resistance. Passive earth resistance has been neglected in design due to a limited amount of full-scale testing. This research presents the results of a combination of hydraulic actuator and eccentric-mass shaker full-scale testing of a pile cap with loose silty sand backfill to quantify the contribution of the passive …


Statnamic Lateral Loading Testing Of Full-Scale 15 And 9 Group Piles In Clay, Rick Davon Broderick Mar 2007

Statnamic Lateral Loading Testing Of Full-Scale 15 And 9 Group Piles In Clay, Rick Davon Broderick

Theses and Dissertations

Studies of seismic and impact loading on foundation piles is an important and a focused interest in the engineering world today. Because of seismic and other natural events are unpredictable, uncontrollable and potentially unsafe it is a vital study to understand the behavior and relationship structures in motion have on there foundation. Statnamic Loading has become a popular method of studying this relationship in a controlled environment. Two groups of 9 and 15 driven hollow pipe piles were tested in saturated clay at the Salt Lake City Airport in July of 2002. The 9-pile group (3x3 configuration) was separated at …
