Critical Ultimate Shear Strength and Shear Force of the footing for beam shear action, kNB.) Critical wide beam nominal shear stress, MPaC.) Ultimate Shear Strength of the footing in punching shear action, kN Please answer it ASAP and correctly for upvotes.A strip footing for a masonry wall is 1.1 m wide and is supported by the soil profile shown in the figure. What design loading can be imposed on the strip footing per meter of length? Use a factor of safety of 3. Ignore the depth factor terms in the bearing capacity calculations. However, you do want to compute the net bearing capacity, so you need to account for the weight of material removed in constructing the footing. To do this assume that the removed weight is equal to the depth of the footing multiplied by the unit weight of the upper soil.
