Syntax

C++

Copy

[SerializableAttribute]
public class Joint : CommonObject, ICloneable, 
	ISerializable

<SerializableAttribute>
Public Class Joint
	Inherits CommonObject
	Implements ICloneable, ISerializable

[SerializableAttribute]
public ref class Joint : public CommonObject, 
	ICloneable, ISerializable

[<SerializableAttribute>]
type Joint =  
    class
        inherit CommonObject
        interface ICloneable
        interface ISerializable
    end

The Joint type exposes the following members.

Constructors

	Name	Description
	Joint	Initializes a new instance of the Joint class. create joint without default properties.
	Joint(NullableDouble)	Initializes a new instance of the Joint class. create joint with properties given in array c.
	Joint(SerializationInfo, StreamingContext)	Initializes a new instance of the Joint class. de-serialization constructor.

Properties

	Name	Description
	c	Gets or sets the joints DOF-stiffness.
	elemIds	Gets or sets the list of element identifiers to which the cross section is to be attached.
	guid	Gets the GUID of the joint.
	name	Gets or sets the name of the cross section.
	props	Gets or sets the joint properties which are the twelve stiffnesses at the end-nodes of the line element. These conditions are tx, ty, tz (translational DOFs) and rx, ry, rz (rotational DOFs) at the two nodes. A value of null means fixation, values of t are in kN/m, values of r in kNm/rad.
	UserData	Gets access to the user-data dictionary. (Inherited from CommonObject.)

Methods

	Name	Description
	AddElemId	add an element identifier to the list of element identifiers which define to which elements the joint definition shall be attached in the course of assemblage.
	addTo(ModelElement)	Attaches this joint to an elements.
	addTo(ListModelElement, IdMapper)	attach this joint to elements.
	addTo(ModelBeam, Model, ListNode)	adds joints to the the endpoints of a beam.
	c_condition	returns list of six doubles for each node which are the spring stiffnesses corresponding to the DOFs. If null there is no joint for the corresponding DOF.
	clearElemIds	empty the list of identifiers to which the cross section shall be attached.
	Clone	shallow clone.
	condition	returns list of six booleans for each node. If true a joint is in effect for the corresponding DOF. nodes indexes start from 0 (starting node); 1 signifies the end-node.
	defaultGuid	Get the Guid of the joint.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetObjectData	Serialize FemMaterial_Isotrop. (Overrides CommonObjectGetObjectData(SerializationInfo, StreamingContext).)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	HasUserData	true if the object has user-data attached. (Inherited from CommonObject.)
	matchId	test whether the cross section matches one of the identifiers given in the list of indexes.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	merge	merge two joints. If there are conflicting stiffness properties for DOFs the smaller stiffness results.
	renewGuid	create a new GUID for the joint.
	renewGuid(Guid)	Sets a given GUID for the joint.
	setDefaults	Set the stiffness to zero.
	springProps	returns finite element spring object for specified end of beam.
	ToString	Returns a string that represents the current object. (Overrides CommonObjectToString.)

Fields

	Name	Description
	c_	list of stiffness for the joint DOFs.
	dofs	number of dofs of the joint.
	elem_ids_	id/regular expressions of element identifiers to which the cross section applies.
	guid_	GUID of the joint.
	name_	unique identifier of a joint a family.
	stiffness_factor	factor for rigid connections relative to the elements stiffness.
