This command is used to construct an elasticBeamColumn element object. The arguments for the construction of an elastic beam-column element depend on the dimension of the problem, ndm:

For a two-dimensional problem:

element elasticBeamColumn $eleTag $iNode $jNode $A $E $Iz $transfTag <-mass $massDens>

For a three-dimensional problem:

element elasticBeamColumn $eleTag $iNode $jNode $A $E $G $J $Iy $Iz $transfTag <-mass $massDens>

---

$eleTag	unique element object tag
$iNode $jNode	end nodes
$A	cross-sectional area of element
$E	Young's Modulus
$G	Shear Modulus
$J	torsional moment of inertia of cross section
$Iz	second moment of area about the local z-axis
$Iy	second moment of area about the local y-axis
$transfTag	identifier for previously-defined coordinate-transformation (CrdTransf) object
$massDens	element mass density (per unit length), from which a lumped-mass matrix is formed (optional, default=0.0)

NOTE:

The valid queries to an elastic beam-column element when creating an ElementRecorder object are 'force'.

EXAMPLE:

element elasticBeamColumn 1 2 4 5.5 100.0 1e6 9; # elastic element tag 1 between nodes 2 and 4 with area 5.5, E 100 and IZ 1e6 which uses transformation 9
