The reinforcing element type IfcReinforcingBarType defines commonly shared information for occurrences of reinforcing bars. The set of shared information may include:
- common properties with shared property sets
- common representations
- common materials
- common composition of elements
It is used to define a reinforcing bar type specification indicating the specific product information that is common to all occurrences of that product type. The IfcReinforcingBarType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcReinforcingBarType are represented by instances of IfcReinforcingBar.
HISTORY New entity in IFC4.
Subtype of reinforcing bar.
The nominal diameter defining the cross-section size of the reinforcing bar.
The effective cross-section area of the reinforcing bar.
The total length of the reinforcing bar. The total length of bended bars are calculated according to local standards with corrections for the bends.
Indicator for whether the bar surface is plain or textured.
Shape code per a standard like ACI 315, ISO 3766, or a similar standard. It is presumed that a single standard for defining the bar bending is used throughout the project and that this standard is referenced from the IfcProject object through the IfcDocumentReference mechanism.
Bending shape parameters. Their meaning is defined by the bending shape code and the respective standard.
The inherited attribute ElementType shall be provided if the PredefinedType is set to USERDEFINED.
Bending parameters must be accompanied by a shape code.
