Why use equivalent‑frame widths around flat slab columns for moment transfer?
Choices
- (A) Slab–column joint flexure needs beam strips wider than a single diagonal strut
- (B) Moment transfer never mobilises torsion in drop capitals
- (C) Equivalent frames delete punching checks entirely
- (D) Column strips ignore lateral load drift compatibility
Correct answer: (A)
Slab–column joint flexure needs beam strips wider than a single diagonal strut
Explanation
ACI-style equivalent frames capture both flexure and shear transfer widths.
