I work on remodels and often need to know if the existing stemwall and footing are adequate for a new point load.
I have a roof beam point load going down to an existing 8in x10ft tall stem wall on 16x8 footing.
This is quite a different instance than a post on a footing. My existing 10ft stem wall would spread that load out across the whole footing at 45 degrees from the point load 10ft above.
Can you tell me the best module to use for this and how to?
Thank you, Barry
