SAFE v12 punching shear
SAFE v12 punching shear
(OP)
Hello guys,
I have a model of a flat plate, with a couple of shear walls on the perimeter. I have trying to verify the punching shear of the columns but for some reason I don't know, SAFE won't calculate the punching shear on the perimeter columns ("N/C" result).
When does SAFE stop calculating punching shear? If the columns are of different dimensions above and below the slab, does SAFE stop its punching shear check?

I hope you can find out in the SAFE folder with manuals and i believe that will give your answer.

My opinion is get the forces for punching shear and do the manual check. We are using SAFE v12 but still I find the some of the results different from manual calculation. It might be the punching area which is the problem.

Yes, that's what I decided in the end. I still hope CSI will actually update SAFE v12 and fix some bugs. I found that, as you thought, the punching area isn't always accurate. Sometimes, for some unknown reasons, SAFE would "ignore" the added thickness from a drop panel.

How do you check local and global bearing stress in SAFE for rafts? How do you check deflection? and differential settlement?
Thanks

I dont know if SAFE can do differential settlement and i will love to know if you get an idea.
Thanks

In showing the actual bearing stresses (which should not be equal nor greater than the allowable bearing stress, qa) which should I use to view or check this? Deformed shape or slab stresses?
In Deformed shape where I can define the contour range. Is this where I can set the limits for allowable bearing stress or is this for settlement?
I am not sure if we can check settlement in deformed shape because there is a limits to be defined, but in other softwares we get the joint displacement to get the max and min settlement then subtract to obtain differential.
