This command is used to construct a SSPquad element object.

element SSPquad $eleTag $iNode $jNode $kNode $lNode $matTag $type $thick <$b1 $b2>


$eleTag unique integer tag identifying element object
$iNode $jNode $kNode $lNode the four nodes defining the element, input in counterclockwise order
$matTag unique integer tag associated with previously-defined nDMaterial object
$type string to relay material behavior to the element, can be either "PlaneStrain" or "PlaneStress"
$thick thickness of the element in out-of-plane direction
$b1 $b2 constant body forces in x- and y-directions, respectively (optional, default = 0.0)




The SSPquad element ...

NOTE:

  1. Valid queries to the SSPquad element when creating an ElementalRecorder object correspond to those for the nDMaterial object assigned to the element (e.g., 'stress', 'strain'). Material response is recorded at the single integration point located in the center of the element.
