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.
