22.214.171.124. sp command¶
sp(nodeTag, dof, *dofValues)¶
This command is used to construct a single-point constraint object and add it to the enclosing LoadPattern.
tag of node to which load is applied.
the degree-of-freedom at the node to which constraint is applied (1 through ndf)
ndf reference constraint values.
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.
