The critical section for punching shear in a footing is at:
RCCFootingsMEDIUM
Choose the correct answer
A
Face of column
B
d/2 from face of column (perimeter d/2 around column)
C
d from face of column
D
Edge of footing
Correct Answer
B. d/2 from face of column (perimeter d/2 around column)
Why is this the answer?
Punching shear: critical perimeter bo = 4(b+d) for square column (b=column side, d=effective depth). Punching shear stress τv = Vu/(bo×d). IS 456: τc_punch ≤ k×τc.
