This command is used to construct an ElasticTubularJoint element object, which models joint flexibility of tubular joints in two dimensional analysis of any structure having tubular joints.

element ElasticTubularJoint $Tag $iNode $jNode $Brace_Diameter $Brace_Angle $E $Chord_Diameter $Chord_Thickness $Chord_Angle


$Tag unique element object tag
$iNode first end node- it is always located on the chord axis
$jNode second end node - it is always located on the chord wall
$Brace_Diameter outer diameter of brace
$Brace_Angle angle between brace and chord axis 0 < Brace_Angle < 90
$E Young's Modulus
$ Chord_Diameter outer diameter of chord
$Chord_Thickness thickness of chord
$Chord_Angle angle between chord axis and global x-axis 0 < Chord_Angle < 90


EXAMPLE:

element ElasticTubularJoint 1 1 2 0.25 45 210E+09 0.5 0.016 45 # Tubular joint having tag 1 which interconnects nodes 1 and 2; brace diameter is 25cm; intersection angle is 45 degrees; Young's modulus of the material used is 210e9; outer diameter and thickness of the chord are 50 cm and 1.6 cm respectively; angle between chord axis and global horizontal axis is 45 degrees.
