How to calculate one way shear in footing
WebFoundation Engineering Chapter 6: Structural Design of Footings 2 6.2 ASSUMPTIONS 1. The footing is assumed to be rigid (the thickness is sufficient enough) for easy calculation. 2. Actually, the soil pressure distribution under a footing is not uniform and depends upon footing rigidity, shape, and depth. Web18 dec. 2024 · The footing is supported by the soil below and the column punching through the footing ( punching shear ,two way shear ) is checked at the critical perimeter , along the surface of a truncated pyramid around the column. Thus, the critical section for the punching shear is taken at a distance d/2 from the periphery of the column.
