8-1 FOOTINGS: CLASSIFICATION AND PURPOSEA footing carrying a single column is called a spread footing, since its function is to "spread"the column load laterally to the soil so that the stress intensity is reduced to a value that thesoil can safely carry. These members are sometimes called single or isolated footings. Wallfootings serve a similar purpose of spreading the wall load to the soil. Often, however, wallfooting widths are controlled by factors other than the allowable soil pressure since wall loads(including wall weight) are usually rather low.
and there is much uncertainty with that design. We will use the USD for spread footing design; however, footing depth equations [Eqs.(8-5)-(8 …
