I am not sure how to deal with this issue, it fails also when the wind loads is set at 1, not sure how to deal with this
Hi Christian!
Thanks for reaching out! As you have Identified yourself there are uplift forces on the beam that’s being supported by your pier, I’d suggest you confirm if that applies to your project. If that’s the case, you can see in this video that if you reduce this uplift load you don’t have too much uplift on the pier anymore. However, if the wind forces on the beam are correct, the uplift on the pier is occurring and you wil lget the fail.
Unfortunately, we currently can’t take the fail check out until we’ve added the feature for uplift capacity checks. I completely understand how this might be frustrating, and I’ve already raised this concern with our team so we can work towards a better solution.
Thank you for your patience and understanding and please let me know if there is anything else I could help you out with.

Does clear calcs consider the weight of the concrete footing as part of the dead load?
Hi @themathguy the calculator let’s you choose wether you want to consider the self-weight or not, check out the screenshot below.
I hope it helps, otherwise, let me know, thank you!
I was surprised that wasn’t the first suggestion for fixing uplift failure, thanks for pointing out where it is at.
Actually, now that I’m looking, this doesn’t appear to be in the spread footing module v16 unless I’m missing something… there’s a calculation of the self weight, but the “consider self weight” line appears to be missing.
Hi @themathguy thanks for your reply. In the Spread Footing module the self-weight is automatically considered, you can see it under the “Applied Loads” section.
I hope that helps!
If you take out your dead and occupancy loads and add a -100 wind uplift does it fail? It does for me, which means while the self weight is being calculated, it’s not actually being applied correctly…
