Element types

JOINTC: Joint interaction element

Active degrees of freedom

1, 2, 3, 4, 5, 6

Additional solution variables

None.

Nodal coordinates required

None. The element nodes do not need to have coordinates defined since the action associated with these elements is defined by specifying the degrees of freedom involved.

Element property definition

Input File Usage

JOINT

Element-based loading

None.

Element output

S11: Total direct force in the first local direction.
S22: Total direct force in the second local direction.
S33: Total direct force in the third local direction.
S12: Total moment about the first local direction.
S13: Total moment about the second local direction.
S23: Total moment about the third local direction.

The relative displacements and rotations corresponding to the forces and moments above are chosen by requesting the corresponding “strains.”

Nodes associated with the element

Two nodes. The rotation at the first node of the element defines the rotation of the local axis system.
