Punching Shear Perimeter & Varying Slab Depths
Punching Shear Perimeter & Varying Slab Depths
(OP)
Hello,
I've done a bit of research and asked around the office for some opinions, but I'd like to hear what everyone else thinks.
I've got a column partially within a slab fold and thus the critical shear perimeter has different depths.
Should I be trying to adopt an 'averaging' methodology for the critical shear perimeter and depth to tensile steel? Or should I be dividing the moment and shear by 4 and checking only Quadrant D using code equations.

Additional info:
- N40 concrete
- P/A = 1.5 MPa
- V* = 850 kN, Mx* = 230 kNm, My* = 170 kNm
- 2N12-400 nominal ligs through 380/350 fold section.
- AS3600 code

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.
