7.11.3.22 IfcTendonType

7.11.3.22.1 Semantic definition

The reinforcing element type IfcTendonType defines commonly shared information for occurrences of tendons. 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 tendon type specification indicating the specific product information that is common to all occurrences of that product type. The IfcTendonType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcTendonType are represented by instances of IfcTendon.

Material Use Definition

An associated material denotes the steel grade, preferably via material classification. A material constituent set or material profile set may be associated if the cable, bonding mortar or corrosion protection, and tendon sheeth are to be described together by the material association.

Geometry Use Definition

The IfcTendonType may define the shared geometric representation for many tendon occurrences. The RepresentationMaps attribute refers to a list of IfcRepresentationMap's, that allow for multiple geometric representations.
