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 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.  |
