Abstract

Tapered steel piles have been used predominantly at JFKIA to provide foundation support for selected structures including “International and Domestic Air Terminals” plus heavily loaded multi-level “Parking Garages”, JFK Airtrain Elevated Guideway, JFK Terminal at Jamaica, Queens, NYC and other facilities. The historical development and comparative evaluation of tapered piles with other pile types are addressed. Results of dynamic measurements to permit evaluation of pile capacity during initial installation and at predetermined subsequent intervals to evaluate set-up (increased capacity with time) are provided. Final selected ultimate pile capacities are always confirmed by standard compression load tests illustrated by an extensive array of pile foundation case histories. Reference has also been made to a report on “Estimating Soil / Pile Set-Up” September 2003, financed by the Wisconsin Department of Highways and the Federal Highway Administration.

Influence of Taper in Selecting Pile Support System or Major Structures

Arlington, Virginia

Tapered steel piles have been used predominantly at JFKIA to provide foundation support for selected structures including “International and Domestic Air Terminals” plus heavily loaded multi-level “Parking Garages”, JFK Airtrain Elevated Guideway, JFK Terminal at Jamaica, Queens, NYC and other facilities. The historical development and comparative evaluation of tapered piles with other pile types are addressed. Results of dynamic measurements to permit evaluation of pile capacity during initial installation and at predetermined subsequent intervals to evaluate set-up (increased capacity with time) are provided. Final selected ultimate pile capacities are always confirmed by standard compression load tests illustrated by an extensive array of pile foundation case histories. Reference has also been made to a report on “Estimating Soil / Pile Set-Up” September 2003, financed by the Wisconsin Department of Highways and the Federal Highway Administration.
