A rectangular footing 2.3 m x 3.2 m x 0.34 m thick supports a
300 mm square column at its center.
Column loads are service conditions:
DL = 341 kN
LL = 216 kN
f’c = 21 MPa
fy = 415 MPa
Concrete cover to the centroid of steel reinforcement = 100
mm
Calculate the ultimate punching shear stress in the slab.
Write your final answer with 2 decimal places if the unit is
MPA.
