Type definition

This enumeration defines the distribution of load values in a curve action or reaction.

HISTORY New enumeration in IFC4

Enumeration definition

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.
