6.1.2.1 IfcBeamTypeEnum

6.1.2.1.1 Semantic definition

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 its 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.
