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. |
