Entity definition

A ramp is a vertical passageway which provides a human or vehicle circulation link between one floor level and another floor level at a different elevation. It may include a landing as an intermediate floor slab. A ramp normally does not include steps.

NOTE  Definition according to ISO 6707-1: Inclined way or floor joining two surfaces at different levels.

The IfcRamp shall either be represented:

NOTE  In case of an IfcRamp being the assembly of all parts of the ramp the aggregation is handled by the IfcRelAggregates relationship, relating an IfcRamp with the related IfcRampFlight and landings, IfcSlab with PredefinedType=LANDING. IfcRailing's belonging to the ramp may also be included into the aggregation.

NOTE  Model View Definitions and implementer agreements may restrict the IfcRamp being an assembly to not have an independent shape representation, but to always require that the decomposed parts have a shape representation. In this case, at least the 'Body' geometric representations shall not be provided directly at IfcRamp if it is an assembly. The 'Body' geometric representation of the IfcRamp is then the sum of the 'Body' shape representation of the parts within the decomposition structure.

HISTORY  New entity in IFC2.0.

IFC4 CHANGE Attribute ShapeType renamed to PredefinedType

Material Solid

The Material Single concept applies to this entity.

The material of the IfcRamp is defined by the IfcMaterial and attached by the IfcRelAssociatesMaterial.RelatingMaterial. It is accessible by the inverse HasAssociations relationship.

Material information can also be given at the IfcRampType, defining the common attribute data for all occurrences of the same type. It is then accessible by the inverse IsDefinedBy relationship pointing to IfcRampType.HasAssociations and via IfcRelAssociatesMaterial.RelatingMaterial to IfcMaterial. If both are given, then the material directly assigned to IfcRamp overrides the material assigned to IfcRampType.



Spatial Containment

The Spatial Containment concept template applies to this entity as shown in Table 210.

RelatingStructureDescription
IfcBuildingStoreyDefault spatial container
IfcBuildingSpatial container for the element if it cannot be assigned to a building storey
IfcSiteSpatial container for the element in case that it is placed on site (outside of building)

Table 210 — IfcRamp Spatial Containment

The IfcRamp, as any subtype of IfcBuildingElement, may participate alternatively in one of the two different containment relationships:



Element Decomposition

The Element Decomposition concept template applies to this entity as shown in Table 211.

IsDecomposedByRelatedObjectsDescription
IfcRampFlightRamps may be decomposed into ramp flights.
IfcSlabRamps may be decomposed into ramp landing, represented by IfcSlab.PredefinedType=LANDING
IfcRailingRamps may be decomposed into railings.

Table 211 — IfcRamp Element Decomposition

If the IfcRamp has components (referenced by SELF\IfcProduct.IsDecomposedBy) then no independent 'Body' geometric representation shall be defined for the IfcRamp. The IfcRamp is then geometrically represented by the geometric representation of its components.

 

ramp
EXAMPLE  Figure 372 illustrates IfcRamp defining the local placement for all components.

Figure 372 — Ramp placement

 


Placement

The Product Local Placement concept template applies to this entity as shown in Table 212.

Table 212 — IfcRamp Product Local Placement

The following restriction may be imposed by view definitions or implementer agreements:



Axis 2D Geometry

The Axis 2D Geometry concept applies to this entity.

The walking line is represented by a two-dimensional open curve as the axis. The curve is directed into the upward direction (direction has to be interpreted as specified at the subtypes of IfcCurve).

NOTE  The 'Axis' representation of IfcRamp may be provided even if the IfcRamp has components with own shape representations.



Body SweptSolid Geometry

The Body SweptSolid Geometry concept applies to this entity.

If the IfcRamp has no components defined (empty set of SELF\IfcProduct.IsDecomposedBy) then the IfcRamp 'Body' geometry may be represented by an own IfcShapeRepresentation.



Body Clipping Geometry

The Body Clipping Geometry concept applies to this entity.
