lateral pressure for design of wall forms
i'm looking at a table based on aci committee 347 pressure formulas for placement of concrete at 10 ft/hr or less. the maximum lateral pressure that i have found for the form work in question is 407 psf or 19.5 kpa.
does this not seem a bit overboard? i have never done forms before so i can't really trust my judgment on this one.
also, will 407 psf be applied on the forms on each side of the wall regardless of the variation of thickness of the wall along its length? or is my understanding of the concept completely wrong?
thanks!
