Defined in File Ifc2x3.h
Definition from IAI: This enumeration defines the different types of linear elements an IfcBeamType object can fulfill:
BEAM: A standard beam usually used horizontally. JOIST: A beam used to support a floor or ceiling. HOLLOWCORE: A wide often prestressed beam with a hollow-core profile that usually serves as a slab component. LINTEL: A beam or horizontal piece of material over an opening (e.g. door, window). 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.
NOTE They are also referred to as “spandrel
panels”, which are parts of a facade and sometimes have supporting consoles for floor slabs integrated.
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
