This comnand is used to construct a single-point constraint object and add it to the enclosing LoadPattern.

sp $nodeTag $dofTag $dofValue

$nodeTag tag of node to which constraint is applied.
$dofTag the degree-of-freedom at the node to which constraint is applied (1 through ndf)
$dofValue reference constraint value.


NOTES:

  1. The $dofValue is a reference value, it is the time series that provides the load factor. The load factor times the reference

value is the constraint that is actually applied to the node.
