• Abstract:
  Many transportation facility structures in Wisconsin are founded on driven round, closed-end, steel, pipe piles. The piles are driven to capacity and then filled with concrete. The Wisconsin Department of Transportation (WisDOT) has designed and driven many of these pipe piles using the Load Factor Design (LFD) methodology. WisDOT’s experience indicates that design pile length estimations have generally been fairly accurate when compared to driven pile lengths. Driven lengths have been determined based on penetration resistance measured in the field using the Wisconsin-modified Engineering News (EN) driving formula, as described in Section 508 of the Standard Specifications for Highway and Structure Construction.
