This enumeration defines the different predefined types of beams that can further specify an IfcBeam or IfcBeamType.
6.1.2.1.2 Type values
Type
Description
BEAM
A standard beam usually used horizontally.
CORNICE
A non-loadbearing beam on the longitudinal edge of bridge slab, usually encasing installations.
DIAPHRAGM
End portion of a girder transmitting loads to supports and providing moment resistance to adjoining segment.
EDGEBEAM
A beam on the longitudinal edge of bridge slab, usually concrete, providing additional stiffening and protection from the elements.
GIRDER_SEGMENT
A segment of a girder (e.g. each span of a continuous girder).
HATSTONE
A beam on top of a retaining wall or a wing wall, preventing earth movement.
HOLLOWCORE
A wide often prestressed beam with a hollow-core profile that usually serves as a slab component.
JOIST
A beam used to support a floor or ceiling.
LINTEL
A beam or horizontal piece of material over an opening (e.g. door, window).
PIERCAP
A transversal beam on top of a pier (on a single column or extending from one column of a pier to another column of the same pier).
SPANDREL
A tall beam placed on the facade of a building. One tall side is usually finished to provide the exterior of the building. Can be used to support joists or slab elements on its interior side.
T_BEAM
A beam that forms part of a slab construction and acts together with the slab which it carries. Such beams are often of T-shape (therefore the English name), but may have other shapes as well, e.g. an L-Shape or an Inverted-T-Shape.
USERDEFINED
User-defined linear beam element.
NOTDEFINED
Undefined linear beam element.
