Not supported yet
A preset transient in the vertical direction shear. This is a linear relationship between the height and the local direction, with the direction being its nominal value at the reference height.

A type of DirectionShearVariation
Properties
DirectionShearVariationType
: stringcoming soon
Defines the specific type of DirectionShearVariation model in use. For a PresetTransient
object, this must always be set to a value of PresetTransient
.
DirectionShearAtStart
: number (rad/m)coming soon
The vertical direction shear at the start of the simulation up to the beginning of the transient. For a full cycle this will also be the value after the transient has completed.
AmplitudeOfVariation
: number (rad/m)coming soon
The maximum amplitude of the variation.
StartTime
: number (s)coming soon
The time into the simulation at which to start the transient (excluding the lead-in time).
DurationOfVariation
: number (s)coming soon
The time taken to complete the transient, whether half-cycle or full-cycle.
VariationShape
: stringcoming soon
The shape of the transient. This can either be a half-cycle (where the shear remains at the initial value plus the amplitude after the transient has been completed) or a full-cycle (where the shear returns to its original value).
