FAQ: How Is The Structural Strength of a Vulcan Earth Anchor System Determined?
Posted on 6th December 2024The Vulcan Earth Anchor
All parts of a Vulcan Earth Anchor System are checked through independent testing. The weakest component’s break load is then reduced by a further 10% and recorded as the Limiting Structural Strength of that anchor system.
This capacity is usually far beyond what the soil will allow the anchor to achieve so, in some cases, especially in well compacted soils or gravel layers, the anchors achieve high loads allowing the designers to use smaller anchors to achieve the design load required, therefore, offering the most cost-effective solution.
The Vulcan Earth Anchor range has been carefully designed and been named based on the holding capacity achieved in medium to poor soil conditions. E.G. an AS-90 anchor supplied on a 20mm galvanised bar system has a limiting structural strength of 169.2kN. However, in medium to poor soil conditions this anchor will achieve a maximum capacity of 90kN. Anchors that are installed into stiffer substrates they will exceed their named loads.
*All kN loadings are based upon the optimal tendon choice for the mechanical Anchoring systems to achieve Ultimate Resistance test*.
Ensuring Accuracy in Anchor Design
To achieve optimal performance, several factors are considered during the design and installation process:
- Soil Testing: Comprehensive soil analysis helps determine the substrate type and its shear strength.
- Anchor Selection: Engineers select the appropriate anchor model and bar system based on project requirements and soil conditions.
- Installation Method: Proper installation is critical to maximise the anchor’s performance and ensure long-term stability.
Sustainability and Longevity
Vulcan Earth Anchors are manufactured using high-quality, recyclable materials, contributing to sustainable construction practices. Their durability ensures a long operational lifespan, reducing the need for replacements and minimising environmental impact.
By combining robust testing, intelligent design, and versatile performance, the Vulcan Earth Anchor System delivers reliable, cost-effective solutions for a wide range of ground anchoring challenges.
