This command is used to construct a single-point non-homogeneous constraint (SP_Constraint) object.
sp $nodeTag $DOFtag $DOFvalue
$nodeTag |
node on which the single-point constraint acts |
$DOFtag |
degree-of-freedom at the node being constrained. Valid range is from 1 through ndf, the number of nodal degrees-of-freedom. |
$DOFvalue |
reference value of the constraint to be applied to the DOF at the node. |
EXAMPLE
sp 3 1 0.1; # impose displacement Dx=0.1 at node 3
