BH.oM.Structure.Constraints.Constraint4DOF

Constraint objects with four degrees of freedom, three translational and one rotational. Used for support or release of 1D analytical elements of 2D analytical objects. The Rotational DOF will correspond to rotation about the axis of the object.

Class structure

Implemented interfaces and base types

The Constraint4DOF is inheriting from the following base type(s) and implements the following interfaces:

Properties

Defining properties

The following properties are defined on the class

Name Type Description Quantity
Name string A unique Name is required for some structural packages to create and identify the object. -
TranslationX DOFType Defines the translational fixity in the X-direction. -
TranslationY DOFType Defines the translational fixity in the Y-direction. -
TranslationZ DOFType Defines the translational fixity in the Z-direction. -
RotationX DOFType Defines the rotational fixity about the axis of the element. -
TranslationalStiffnessX double Defines the stiffness in X-direction. This will only be active when corresponding degree of freedom has a DOFType with a stiffness dependency, such as Spring. ForcePerUnitLength [N/m]
TranslationalStiffnessY double Defines the stiffness in Y-direction. This will only be active when corresponding degree of freedom has a DOFType with a stiffness dependency, such as Spring. ForcePerUnitLength [N/m]
TranslationalStiffnessZ double Defines the stiffness in Z-direction. This will only be active when corresponding degree of freedom has a DOFType with a stiffness dependency, such as Spring. ForcePerUnitLength [N/m]
RotationalStiffnessX double Defines the stiffness for rotation about the axis of the element. This will only be active when corresponding degree of freedom has a DOFType with a stiffness dependency, such as Spring. MomentPerUnitAngle [N.m/rad]

Derived properties

The following properties are defined as extension methods in one of the BHoM_Engines

Name Type Description Quantity Engine
Description string Generates a default description for the Constraint4DOF based on the constraints at each degree of freedom. - Structure_Engine
DescriptionOrName string Gets the name from a IProperty. If null or empty, a default description name is provided instead. - Structure_Engine
IDescription string Generates a default description for the IProperty, based on its properties. - Structure_Engine
IsNull bool Checks if a Constraint4DOF is null and outputs relevant error message. - Structure_Engine
IsNumericallyDependent bool Returns true if any of the degrees of freedom is of a value based type or the values are non-zero. - Structure_Engine
