7.10.2.8 IfcStructuralCurveActivityTypeEnum
7.10.2.8.1 Semantic definition
This enumeration defines the distribution of load values in a curve action or reaction.
7.10.2.8.2 Type values
| Type | Description |
|---|---|
CONST
|
The load has a constant value over its entire extent. |
DISCRETE
|
The load is specified as a series of discrete load points. |
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. |
LINEAR
|
The load value is linearly distributed over the load's extent. |
PARABOLA
|
The load value is distributed as a half wave described by a symmetric quadratic parabola. |
POLYGONAL
|
The load consists of several consecutive linear sections. |
SINUS
|
The load value is distributed as a sinus half wave. |
USERDEFINED
|
The load distribution is user-defined. |
NOTDEFINED
|
The load distribution is undefined. |
