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
