Semantic definitions at the type

Type definition

This enumeration distinguishes between different types of structural 'curve' members, such as cables.

HISTORY New enumeration in IFC2x2.

IFC4 CHANGE Renamed from IfcStructuralCurveTypeEnum.

Enumeration definition

Constant	Description
RIGID_JOINED_MEMBER	A member with capacity to carry transverse and axial loads, i.e. a beam. Its actual joints may be rigid or pinned. Typically used in rigid frames.
PIN_JOINED_MEMBER	A member with capacity to carry axial loads only, i.e. a link. Typically used in trusses.
CABLE	A tension member which is able to carry transverse loads only under large deflection.
TENSION_MEMBER	A member without compressional stiffness.
COMPRESSION_MEMBER	A member without tensional stiffness.
USERDEFINED	A specially defined member.
NOTDEFINED	A member without further categorization.
