How To Design Helical Piles
Design Helical Piles - Foundation Repair Network
How to Design Helical Piles per the 2009 International Building Code by Darin Willis, P.E.1 ABSTRACT Helical piles and anchors have been used in construction applications for more than 150 years. The first recorded use of helical piles was in 1836 by Alexander Mitchell when he used helical piles to underpin the Maplin Sands Lighthouse in England. More Information
DESIGN, INSTALLATION AND TESTING OF HELICAL PILES & ANCHORS
What is a Helical Anchor/Pile? • A helical anchor/pile consists of one or more helix-shaped bearing plates attached to a central shaft, which is installed by rotating or "torqueing" into the ground. Each helix is attached near the tip, is generally circular in plan, and formed into a helix with a defined pitch. Helical anchors/piles derive ... More Information
Quick Design Guide for Screw Piles and Helical Anchors
1.4 Tension Loading of Helical Anchors in SAND The design of deep single-helix Helical Anchors under tension in sands is essentially the same as for compression loading of Screw-Piles in sands. The design steps are: 1. Estimate or determine the design value of friction angle, φ’, from appropriate lab or field tests; 2. More Information
Helical Pile Foundation Design Guide: Anchors & Screw Piles
Helical Piles & Anchors Design Guide. For the vast majority of consulting engineers, helical piles and anchors will never be an everyday, every week, every month, or even a yearly design and application task. Many engineers—though they may learn about helical foundations at a seminar or by use on a specific project—are either reluctant to ... More Information

standing of the design process of helical piles and the intent of the code. SECTION 1802 - DEFINITIONS Section 1802.1 defines a helical pile as: Helical Pile: Manufactured steel deep foundation element consisting of a central shaft and one or more helical bearing plates. A helical pile is installed by rotating it into the ground. Each helical ... More Information
Supportworks Design Examples - Helical Piles
Helical piles are proposed to support a new structure. The proposed pile layout is shown on the foundation plan along with a design working load of 30 kips per pile with a Factor of Safety (FOS) = 2. Preliminary product selection suggests that the Model HP288 helical pile is the best fit for this load condition with an ultimate torque-rated ... More Information

Helical Piles | Geoengineer.org
Helical piles also can be installed in conditions that are unsuitable for cast-in-place concrete piles, like sites with high water tables or collapsing soils. In addition, helical piles are ready to accept design loads after installation, unlike cast-in-place concrete piles that must set. More Information
Helical Piles Design Software - DeepEx
HelixPile can design both Single Helical Piles, and Pile Groups with multiple piles (the additional optional module Pile Groups is required). The software can also design Pile Rafts, considering the combined effect of the soil below the raft (additional module to our Pile Group option). HelixPile can perform both vertical and lateral pile analysis. More Information
