Afternoon all,
As you probably know, SAFE will check "punching shear" for spring supports, which we would use to model piles. I was curious how it could possibly check punching shear for these elements since they are not assigned a length or width, which one would need to calculate a critical perimeter.
Looking in to the punching shear calculation, I found that the calculated critical perimeter is a square with each side equal to d (so critical perimeter = d*4). This means that SAFE is assuming the the pile support is an infinitely-small square support. Has anyone had any experience, or maybe reached out to CSI regarding this decision? Though punching shear in piles don't often seem to be a problem for me, this could lead to an overly-conservative design if left to use the software.
Any thoughts?
Thanks!
