WebSep 28, 2024 · With our new-found value of q_u qu, we can find the factored shear. The ACI-318-14 code (*Cl 7.4.3.2*) specifies that the critical shear section should be taken at a distance d d from the face of the wall. With our 12-inch thick footing, we need a minimum of 3 inches cover (*ACI 318-14, Table 20.6.1.3.1*). Web*The example works with net bearing stress and only calculates the length of footing required, while we calculate gross bearing stress and work directly with stresses. The utilization ratios are thus compared and give essentially the same result - the 0.7% difference comes from rounding errors, and the example ignoring the weight of soil ...
