This command is used to construct a two-dimensional beam-column-joint element object. The element may be used with both two-dimensional and three-dimensional structures; however, load is transferred only in the plane of the element.

$Tag	unique element object tag
$Nd1 $Nd2 $Nd3 $Nd4	four nodes
$Mat1	uniaxial material tag for left bar-slip spring at node 1
$Mat2	uniaxial material tag for right bar-slip spring at node 1
$Mat3	uniaxial material tag for interface-shear spring at node 1
$Mat4	uniaxial material tag for lower bar-slip spring at node 2
$Mat5	uniaxial material tag for upper bar-slip spring at node 2
$Mat6	uniaxial material tag for interface-shear spring at node 2
$Mat7	uniaxial material tag for left bar-slip spring at node 3
$Mat8	uniaxial material tag for right bar-slip spring at node 3
$Mat9	uniaxial material tag for interface-shear spring at node 3
$Mat10	uniaxial material tag for lower bar-slip spring at node 4
$Mat11	uniaxial material tag for upper bar-slip spring at node 4
$Mat12	uniaxial material tag for interface-shear spring at node 4
$Mat13	uniaxial material tag for shear-panel
$eleHeightFac	floating point value (as a ratio to the total height of the element) to be considered for determination of the distance in between the tension-compression couples (optional, default: 1.0)
$eleWidthFac	floating point value (as a ratio to the total width of the element) to be considered for determination of the distance in between the tension-compression couples (optional, default: 1.0)
