Continuous Footing Design at Tilt wall Panel Jambs

[steeledan]

I'm designing a tilt wall bldg that is essentially swiss cheese - tons of opngs in most all of the panels. In looking at the continuous footing design under the panels, is it fair to ignore the opngs and calc required allowable bearing based on a solid wall w/ whatever other gravity lds are framing in on a per ft basis? Or do I have to look at each individual panel jamb (already did for the actual jamb design...) and figure out the reaction at the base of the jamb, divide it over the jamb length and provide a ftg for that load? If it's the latter, it means really wide spread ftgs at every jamb, which doesn't seem normal.

Continuous footings can be used, provided they are stiff enough and strong enough to distribute the load. This would be a more common approach than providing individual spread footings. Think of the footing as a beam supported by the jambs, with everything just turned upside down. You will obviously need both top and bottom reinforcement in the footing.
