| Structural Curve Activity Type Enum |
| Item | SPF | XML | Change | Description | IFC2x3 to IFC4 |
|---|---|---|---|---|
| IfcStructuralCurveActivityTypeEnum | ADDED |
This enumeration defines the distribution of load values in a curve action or reaction.
HISTORY New enumeration in IFC4
| Constant | Description |
|---|---|
| CONST | The load has a constant value over its entire extent. |
| LINEAR | The load value is linearly distributed over the load's extent. |
| POLYGONAL | The load consists of several consecutive linear sections. |
| EQUIDISTANT | The load consists of n consecutive sections of same length and is specified by n+1 load samples. The interpolation type over the segments is not defined by this distribution type but may be qualified in IfcObject.ObjectType based on additional agreements. |
| SINUS | The load value is distributed as a sinus half wave. |
| PARABOLA | The load value is distributed as a half wave described by a symmetric quadratic parabola. |
| DISCRETE | The load is specified as a series of discrete load points. |
| USERDEFINED | The load distribution is user-defined. |
| NOTDEFINED | The load distribution is undefined. |
