DFI publishes helical pile foundation design guide23 July 2019
New Jersey – DFI announced July 22 the first edition of the new Helical Pile Foundation Design Guide. The guide was produced by the DFI Helical Piles and Tiebacks Committee under the leadership of Gary L. Seider, chair; Wayne Thompson, Design Guide Sub-Committee chair, editor; and Karen Dawson, contributor and editor.
DFI said: "This short, easy-to-follow guide is intended for the preliminary design and selection of helical piles and anchors."
The guide covers applications, terminology, advantages and limitations, geotechnical and structural design methods, corrosion protection, load testing, quality control and assurance, and references. This document is intended to be used by engineers and designers with appropriate background knowledge of theoretical soil mechanics and foundation design methods.
The guide is available at www.dfi.org/publications.asp. The cost is USD 30 for DFI members and USD 50 for nonmembers.
Other publications developed by the DFI Helical Piles and Tiebacks Committee include:
Model Specification for Helical Anchor Foundations Tension Applications: a practical guidance for the specification of helical anchors. Model performance specification language is provided for the design, construction and testing of helical anchorages for tension applications. Typical tension applications include earth retention and shoring, transmission tower guy tiedowns, and buoyancy/uplift protection.
Model Specification for Helical Pile Foundations Compression Applications: practical guidance for the specification of helical pile foundations. Model performance specification language is provided for the design, construction and testing of helical piles for compression, tension and/or lateral loading applications. Typical helical pile foundation applications include new foundation construction, foundation repair and existing foundation augmentation.
Both publications can be downloaded at [www.dfi.org/publications.asp|www.dfi.org/publications.asp] for free for DFI members and $50 for nonmembers.
