A square footing 2.5m x 2.5 m supports a square column 300mm x 300mm at its center. Concrete cover to bar centroid = 100mm. Ultimate load combination is 1.2DL + 1.6L. Column loads aee service conditions: DL = 680 kN LL = 400kN f'c = 20.7 Mpa fy = 275 MPa Calculate the nominal punching-shear stress acting at the critical section of the footing slab if the thickness of the slab is 450 mm. (Correct Answer 1.99)
