This command is used to construct a ModelasticBeam2d element object. The arguments for the construction of an elastic beam-column element with stiffness modifiers is for 2-D problems

element ModelasticBeam2d $eleTag $iNode $jNode $A $E $Iz $K11 $K33 $K44 $transfTag

---

$eleTag	unique element object tag
$iNode $jNode	end nodes
$A	cross-sectional area of element
$E	Young's Modulus
$Iz	second moment of area about the local z-axis
$K11	stiffness modifier for translation
$K33	stiffness modifier for translation
$K44	stiffness modifier for rotation
$transfTag	identifier for previously-defined coordinate-transformation (CrdTransf) object

NOTE:

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

EXAMPLE:

element ModelasticBeam2d 1 2 4 5.5 100.0 1e6 4.0 4.0 2.0 1; # elastic element tag 1 between nodes 2 and 4 with area 5.5, E 100 and IZ 1e6 with K11=K33=4.0, K44=2.0 which uses transformation 1
