FOUNDATION WALLS

Foundation walls provide a ground-level edge for the building and support for elements of the building. In addition to these usual functions they often serve a number of functions for the building foundation system. Some of these are as follows:

Walls of some length and height typically form stiff beamlike elements. Their structural potential in these cases is often used for additional purposes: they distribute or equalize the load.

Walls may be used as spanning members, carrying their own weight as well as some supported loads. This is often the case in buildings with deep foundations and a column structure. Deep foundation elements are placed under the columns, and walls are used in order to span from column to column. This can also be the case with bearing foundations if the column footings are quite large and reasonably closely spaced; the stiff wall then is actually bearing not on its own footing but tends to span between the larger footings.

When columns occur in the same plane as a foundation wall, many different relationships for the structural action of the walls, columns, and column foundations are possible. If the walls and columns are monolithically constructed, the walls generally share the load to some extent.
