IfcReinforcingMesh

Definition from IAI: A series of longitudinal and transverse wires or bars of various gauges, arranged at right angles to each other and welded at all points of intersection; usually used for concrete slab reinforcement. Also known as welded wire fabric.

Property Set Use Definition:

The property sets relating to the IfcReinforcingMesh are defined by the IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to the IfcReinforcingMesh are part of this IFC release:

Pset_ReinforcingBarBendingsBECCommon: common property set for all IfcReinforcingMesh occurrences for bending information according to the Finnish BEC-standard.

Geometry Use Definitions:

The geometric representation of IfcReinforcinMesh is given by the IfcProductDefinitionShape, allowing multiple geometric representations. Included are:

Local Placement
The use of local placement is defined in the supertype IfcBuildingElementComponent.

Standard Geometric Representation
The use of Standard Geometric Representations is defined in the supertype IfcBuildingElementComponent.

Attribute definitions:

MeshLength	:	The overall length of the mesh measured in its longitudinal direction.
MeshWidth	:	The overall width of the mesh measured in its transversal direction.
LongitudinalBarNominalDiameter	:	The nominal diameter denoting the cross-section size of the longitudinal bars.
TransverseBarNominalDiameter	:	The nominal diameter denoting the cross-section size of the transverse bars.
LongitudinalBarCrossSectionArea	:	The effective cross-section area of the longitudinal bars of the mesh.
TransverseBarCrossSectionArea	:	The effective cross-section area of the transverse bars of the mesh.
LongitudinalBarSpacing	:	The spacing between the longitudinal bars. Note: an even distribution of bars is presumed; other cases are handled by Psets.
TransverseBarSpacing	:	The spacing between the transverse bars. Note: an even distribution of bars is presumed; other cases are handled by Psets.
