Helix Capacity Calculator
The Helix Capacity Calculator is a vital tool used in construction and engineering to estimate the load capacity of helical anchors or piles. It calculates the capacity of a helix (in pounds or Newtons) based on various input parameters related to soil properties and the helix’s design.
Formula of Helix Capacity Calculator
The formula used for the Helix Capacity Calculator is as follows:
Qh = A * c * Nc * F * L
Where:
- Qh represents the capacity of the helix (in pounds or Newtons).
- A is the area of the helix (in square feet or square meters).
- c denotes the cohesion of the soil (in pounds per square foot or Pascals).
- Nc signifies the bearing capacity factor related to the angle of internal friction of the soil.
- F is the reduction factor, typically used for safety (commonly ranging from 0.5 to 0.6).
- L represents the depth of the helix plate below the ground surface (in feet or meters).
This formula serves as a fundamental basis for estimating the load-bearing capacity of helical structures, aiding in the design and implementation of various construction projects.

Example of Helix Capacity Calculator
Consider a scenario where the area of the helix is 20 square meters, soil cohesion is 500 Pascals, bearing capacity factor (Nc) is 1.5, reduction factor (F) is 0.6, and the depth (L) is 3 meters. Plugging these values into the formula:
Qh = 20 * 500 * 1.5 * 0.6 * 3 Qh = 5400 Newtons (approx.)
This exemplifies how the Helix Capacity Calculator operates, providing users with the estimated load capacity based on input parameters.
Most Common FAQs
