IfcStructuralCurveTypeEnum

Definition from IAI: This type definition shall be used to distinguish between different types of structural 'curve' members, such as cables. The IfcStructuralCurveTypeEnum type is referenced by the entity IfcStructuralCurveMember.

- 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.

> HISTORY: New type in Release IFC2x Edition 2.
