IfcReinforcementDefinitionProperties
Definition from IAI: An
IfcReinforcementDefinitionProperties defines the cross section
properties of reinforcement included in reinforced concrete building elements.
The property set definition may be used both in conjunction with insitu and
precast structures.
HISTORY New entity in IFC
Release 2x2
General usage:
This subtype of IfcPropertySetDefinition is used to define the
reinforcement properties in early design stages, such as in requirement
definition or scheme design. In later design stages explicit instances of
subtypes of IfcReinforcingElement are used. The intended usage may be
indicated using the DefinitionType attribute value as a designator:
recommended values are 'Reinforcement area requirement' or 'Reinforcement
configuration requirement'. Other values may be used according to local
standards.
Only one property set definition of this kind is used for each concrete
building element in each intended usage indicated by the DefinitionType
attribute value. This set then defines a list of cross section properties in a
discrete number of longitudinal sections as instances of
IfcSectionReinforcementProperties (one for each structural reinforcement
bar role), which in turn have a section cross section property defined as a
profile and a number of reinforcement properties, one for each steel grade /
bar type.
