Speaking of helical earth anchors and wind loads reminds me?
I am researching a method to connect helical earth anchors directly to Simpson frame hold-downs like the PHD series.
Most of the helical systems intended for anchoring temporary buildings have a coil strap or cable that is intended to wrap over or through the structure.
The top end of the helical anchor would need to have a threaded end to receive a threaded rod coupler. Most of the helical anchors I have seen rated in the 2500# range have a proprietary end.
I think there may also be an issue with pre-loading the earth anchor.
