For interior slab–column punching checks, which critical-section outline best matches the usual two‑way shear perimeter defined at d/2 from the column faces?
Choices
- (A) Column face outline only
- (B) Closed polygon offset d/2 from column faces along both slab axes
- (C) Zero-offset circle about column centroid
- (D) Building façade perimeter outline
Correct answer: (B)
Closed polygon offset d/2 from column faces along both slab axes
Explanation
The shear perimeter traces the punching cone breakout path.
