Residential propane tank anchorage

[AaronMcD]

I am required to provide anchorage information for a couple residential propane tanks - 1150 gallons each. They look similar to the tanks you find at the gas station propane refill.

ASCE 7-15 requires 8x diameter gauge for steel anchors in concrete (such as an embedded sleeve), in addition to concrete breakout and pull out being higher than steel failure (SDC C and up).

Some members of the construction team and propane supplier sent some stuff out pertaining to "eye bolt" location. Before I go ask them what the hell an eye bolt is for, I thought I'd ask on here. I'm assuming an eye bolt would be to strap the tank down perhaps? But that doesn't meet ASCE requirements. Is this a common way tanks are anchored? Are most residential propane tanks anchored ignoring ASCE 7 requirements?

Google eyebolt. They probably install concrete anchors with eyebolts under the tanks. Then, straps of some sort attach to the eyebolts.

Have a look at this document.......It looks like there are several different ways to anchor the tanks.

Aaron, my understanding of the 8x stretch length is for elevated tanks, not ground supported.

edit: I reviewed ASCE 7-10 section 15.7.5 and don't see this distinction anywhere, my apologies.

For eye-bolts, just wrap the top 1/4 of the bolt in duct tape 2-3 times and this will provide the "Stretch length" required. Do you embedment calcs from there.
