Joint Class |
Represents the hinge conditions at the start- and end-point of a line element.
Inheritance HierarchyNamespace: Karamba.Joints
Assembly: KarambaCommon (in KarambaCommon.dll) Version: 1.0.0.0 (1.0.0.0)
SyntaxThe Joint type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | Joint |
create joint without default properties
|
| Joint(NullableDouble) |
create joint with properties given in array c
|
Properties| Name | Description | |
|---|---|---|
 | c |
set and get the joints DOF-stiffness
|
| elemIds |
return list of element identifiers to which the cross section is to be attached.
|
| guid |
GUID of the joint
|
| name |
set/get the name of the cross section
|
| props |
give array access to cross section properties which are the twelve conditions 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.
|
Methods| Name | Description | |
|---|---|---|
| AddElemId |
add an element identifier to the list of element identifiers which define to which elements the cross
SectionForce shall be attached in the course of assemblage.
|
| addTo(ModelElement) |
attach this joint to an elements
|
| addTo(ListModelElement, ItemSelector) |
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 | |
| 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.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| 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.) |
| renewGuid |
create a new GUID for the joint
|
| renewGuid(Guid) |
set a given GUID for the joint
|
| setDefaults | |
| springProps |
returns finite element spring object for specified end of beam.
|
| ToString | Returns a string that represents the current object. (Overrides ObjectToString.) |
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 cross section within a family |
| stiffness_factor |
factor for rigid connections relative to the elements stiffness
