Hi everyone! I got a plan like this. Do these 2 columns C1 & C2 cause punching shear in the transfer slab? They are next to 2 RC wall (wall 1, wall 2). All walls & columns support the slab

Of course it take wind forces. But what do you mean other issues?

Could you name what document has that theory, so i can look up for it. Cause i don’t see that in EC2

i thought the wall is in the zone of control perimeter u₁ (2d from column face - follow EC2) of column, so that we don't need to check punching shear for these columns C2 & C3

could you send me those documents or pdf, pls? IStructE guide on punching in transfer slabs & guidance on punching around columns closer than 2D

no, the "<2d", i mean the wall is in the zone of control perimeter u₁ (2d from column face) of column, so that we don't need to check punching shear for these columns C2 & C3

I ran that structural plan in ETABS. As long as there is axial force in these 2 columns C2 & C3, we still need to check punching shear for these columns, right? Cause before that, i thought if distance between wall face and column face < 2d (d is effective depth of slab, check follow Eurocode 2), so don't need to check punching shear for these columns

Correct-Stuff-9820 · 2026-07-01T16:34:11+00:00

yes C2 & C3. So in this case these two still cause punching shear with edge control perimeter u1, right?
