WALL DESIGN - OUT OF PLATE SHEAR
WALL DESIGN - OUT OF PLATE SHEAR
(OP)
hi just like to inquire some insight pertaining to wall out of plane shear.
Based on ACI 318-08, out of plane shear shall be design same as slab and footing ( ACI318-08 11.9.1) where Vc is calculated based on the perimeter of it's critical section for shear, using STAAD plate analysis I would be able to get the SQY and SQX. SRSS the two, will give me the ultimate shear (Vu).
My question is, what perimeter should i be using? would it be the dimension of the plate?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
RE: WALL DESIGN - OUT OF PLATE SHEAR
" In this case it's the cross section of the wall", do you mean, the wall peripheral punching area? would it be the perimeter of the plate times "d"?
about the SRSS thing, it is as Vu = sqrt [ (SQY*length)^2 + (SQX*width)^2 ] * d,
correct me if im wrong, but my understanding of the ACI in calculating the out of plane shear of wall is as a punching shear, Vc = 0.17 sqrt (F'c) bo d (ACI 318-08 11.11.3.1)
if the orthogonal transverse shear components will be analysed independently, would it like a beam shear? where in the section involve is the unit length of SQX times d? is that what you meant about the " cross section of the wall " ? , if so that is what i usually do, but i got confused because ACI is telling me to consider out of plane as a shear at slab and footing.
hope you could enlighten me, thanks

RE: WALL DESIGN - OUT OF PLATE SHEAR
thats is why i come about the punching calculation. my interpretation might not be correct that is why im seeking for further opinion and practices.

Non the less thanksthank you. Well considering one way shear and checking SQY and SQX independently is a more conservative approach than what im thinking of. Haha
