ENUMERATION

- FOOTING_BEAM Footing elements that are in bending and are supported clear of the ground. They will normally span between piers, piles or pile caps. They are distinguished from beams in the building superstructure since they will normally require a lower grade of finish. They are distinguished from STRIP_FOOTING since they are clear of the ground surface and hence require support to the lower face while the concrete is curing.
- PAD_FOOTING An element that transfers the load of a single column (possibly two) to the ground.
- PILE_CAP An element that transfers the load from a column or group of columns to a pier or pile or group of piers or piles.
- STRIP_FOOTING A linear element that transfers loads into the ground from either a continuous element, such as a wall, or from a series of elements, such as columns.
- USERDEFINED Special types of footings which meet specific local requirements.
- NOTDEFINED The type of footing is not defined.
