Semantic definitions at the entity

Entity definition

IfcSectionReinforcementProperties defines the cross section properties of reinforcement for a single longitudinal piece of a cross section with a specific reinforcement usage type.

HISTORY New entity in IFC2x2.

Several sets of cross section reinforcement properties represented by instances of IfcReinforcementProperties may be attached to the section reinforcement properties (IfcReinforcementDefinitionProperties of IfcStructuralElementsDomain schema), one for each combination of steel grades and reinforcement bar types and sizes.
