Displacement-Based Beam-Column Element

This command is used to construct a dispBeamColumn element object, which is a distributed-plasticity, displacement-based beam-column element.

element dispBeamColumn $eleTag $iNode $jNode $numIntgrPts $secTag $transfTag <-mass $massDens>

$eleTag

unique element object tag

$iNode

$jNode

end nodes

$numIntgrPts

number of integration points along the element.

$secTag

identifier for previously-defined section object

$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)

The integration along the element is based on the Gauss-Legendre quadrature rule (REF???).

The element is prismatic, i.e. the beam is represented by the section model identified by $secTag at each integration point.

The valid queries to a displacement-based beam-column element when creating an ElementRecorder object are 'force,' 'stiffness,' and 'section $secNum secArg1 secArg2...' Where $secNum refers to the integration point whose data is to be output.
