Deep Footing Design Based on ACI 318-14

Deep Footing Design Based on ACI 318-14

The shallow foundations are used in case of small buildings or structures, which carry lesser loads, and hencethe loads are dissipated into the soil mass at much lower depth. However when we are considering largestructures, which carry heavy loads, the loads are dissipated at greater depths where usually the soil bearingcapacity is quite high. 

 

One guideline of differentiating between the shallow and deep foundations is that incase of the deep foundations the depth of foundations is more than the dimension of the structure (usuallythe width is considered as the dimension).
