IFC (IFC4X3) development IfcReinforcementBarProperties Semantic definition

IfcReinforcementProperties defines the set of properties for a specific combination of reinforcement bar steel grade, bar type and effective depth.

The total cross section area for the specific steel grade is always provided. Additionally also general reinforcing bar configurations as a count of bars may be provided as defined in attribute BarCount. In this case the nominal bar diameter should be identical for all given bars as defined in attribute NominalBarDiameter. Entity inheritance Attributes

IfcReinforcementBarProperties (6)
1 TotalCrossSectionArea IfcAreaMeasure

The total effective cross-section area of the reinforcement of a specific steel grade.

2 SteelGrade IfcLabel

The nominal steel grade defined according to local standards.

3 BarSurface OPTIONAL IfcReinforcingBarSurfaceEnum

Indicator for whether the bar surface is plain or textured.

4 EffectiveDepth OPTIONAL IfcLengthMeasure

The effective depth, i.e. the distance of the specific reinforcement cross section area or reinforcement configuration in a row, counted from a common specific reference point. Usually the reference point is the upper surface (for beams and slabs) or a similar projection in a plane (for columns).

5 NominalBarDiameter OPTIONAL IfcPositiveLengthMeasure

The nominal diameter defining the cross-section size of the reinforcing bar. The bar diameter should be identical for all bars included in the specific reinforcement configuration.

6 BarCount OPTIONAL IfcCountMeasure

The number of bars with identical nominal diameter and steel grade included in the specific reinforcement configuration.
