4.8.1.3. sp command¶
- sp(nodeTag, dof, dofValue)¶
This command is used to construct a single-point constraint object and add it to the enclosing LoadPattern.
nodeTag
(int)tag of node to which load is applied.
dof
(int)the degree-of-freedom at the node to which constraint is applied (1 through ndf)
dofValue
(float)reference constraint value.
Note
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.
