Places column footings, selected from the catalog, in the model. You can place footings before or after columns are placed in the model. The software creates a relationship between the footing and the member end to which the footing connects.

There are two types of footings that you can place: single and combined. Single footings create a one-to-one relationship between the column and the footing. Combined footings create a many-to-one relationship between a multiple columns and a single footing.

The bottom elevation of the footing can optionally be associated with a reference plane. If the reference plane moves, the footing height adjusts automatically to the new elevation of the plane. Not all footing types support associated planes. Footing types that do not support associated planes have a Number of Supporting value of zero in the catalog.

A footing is used to transfer the loads of a column to the ground or sub-structure and to provide mounting stability for the supported column. A typical footing is comprised of:

  • A base that supports one or more piers. Some footings for light-weight structures, such as a light pole, do not have a base.

  • A pier that rests on the base and supports the grout layer. Some footings do not have a pier in which case the grout is put directly on the base.

  • A grout layer that rests on the pier and supports the base plate.

  • A base plate that rests on the grout layer and is welded to the supported column.

You can place base plates using the Place Assembly Connection Command.

Helpful things to know about footings:

  • Combined footings require a minimum of two columns for placement. If you remove columns from a combined footing such that a single column remains, the software changes the combined footing to a single-type footing supporting the remaining column.

  • When placing a combined footing with a merged pier, all columns must have the same bottom elevation. The software will not allow a column with a different bottom elevation to be added to the merged pier.

  • The software places key points and control points that can be selected as layout points in drawings on combined footings. Key points are placed at the vertices of slabs and piers. Control points are placed at column locations.
