Helical Anchors Capacity
CHANCE HELICAL ANCHOR/PILE BEARING CAPACITY
Determination of helix capacity in a cohesive or fine-grained soil can be accomplished with Equation 5-8 with the second term eliminated. When this equation is applied to helical anchors/piles, the Nc factor is taken to be 9, as it is in other deep applications, provided the installation depth below grade is greater than five times the diameter of the top most helix.

Engineering Design Manual - Helical Anchors Inc
The bearing capacity of a helical anchor varies depending on many factors such as soil properties and conditions, anchor design characteristics, installation parameters, and load type (tension, compression, shear and/or overturning). The equations used to predict capacity of helical anchors in tension and/or compression More Information

Brace Badger Helical Anchor System - Meadow Burke
CAPACITY TO TORQUE RATIO F Helical anchor installation involves screwing the anchor into theground and applying a constant downward force. The holding capac-ity of the anchor is proportionate to the finalinstallation torque. Thefollowing equation can be used to determine holding capacity. Badger Capacity = K x T More Information
Quick Design Guide for Screw Piles and Helical Anchors
The ultimate capacity of multi-helix Screw-Piles in compression and Helical Anchors in tension with a helix spacing/diameter ration > 3 is often taken as the summation of the capacities of the individual plates: Q M = ΣQ H [2.1] where: Q M = Total Capacity of a Multi-Helix Screw-Pile/Helical Anchor Q H = Capacity of an Individual Helix More Information

helical plates welded to the shaft to create a ―screw anchor‖. Helical anchors are primary designed and constructed to provide the uplift resistance to the foundation of a structure. General review consists of research papers on various aspects of investigations on helical anchors like their pullout capacity in clay and sand, stress More Information
Load Capacity and Pullout Strength | American Earth Anchors
About Load Capacity, Pullout Strength & Proof Testing. The only method of accurately predicting the pullout strength of any anchor at any specific site is by an on-site proof test of the anchor under local conditions, installed and loaded in the same manner as for the intended application. Determining load capacity is an inexact science limited ... More Information
Helical Piles, Helical Anchors & Helix Anchors | Chance ...
Helical plates are spaced at distances far enough apart that they function independently as individual bearing elements; consequently, the capacity of a particular helix on a helical anchor/pile shaft is not influenced by the helix above or below it. For more than 100 years, CHANCE helical piles have been the helical of choice. More Information

HELICAL PILES ANCHORS II. DESIGN REQUIREMENTS A. Shaft Type of Helical Pile/Anchor There are 4 basic types of helical piles available. The following is a brief summary of the 4 different types of helicals. • Type 1 - Square Shaft Square shaft piles are more efficient than pipe shaft helical piles in regards to capacity derived from More Information
CHANCE Helical Anchors: Ground Screw Foundation Anchors
Helical bearing plates have a standard 3" pitch and are spaced at far enough distances from enough apart that they bear load independently of each other; therefore, the load capacity of one is not influenced by adjacent plates. More Information
