This commnand allows the user to construct a LoadPattern object. Each plain load pattern is associated with a TimeSeries object and can contain multiple NodalLoads, ElementalLoads and SP_Constraint objects. The command to generate LoadPattern object contains in { } the commands to generate all the loads and the single-point constraints in the pattern. To construct a load pattern and populate it, the following command is used:

pattern Plain $patternTag $tsTag <-fact $cFactor> {
load...
eleLoad...
sp...
...
}


NOTES:

  1. The command to generate a LoadPattern contains in { } the commands to generate all the loads and single-point constraints..
$patternTag unique tag among load patterns
$tsTag the tag of the time series to be used in the load pattern
$cFactor constant factor (optional, default=1.0)
load... command to nodal load
eleLoad ... command to generate elemental load
sp ... command to generate single-point constraint


<uml> abstract class ElementLoad abstract class TimeSeries LoadPattern o- "one" TimeSeries LoadPattern o- ElementLoad LoadPattern o- NodalLoad LoadPattern o- SP_Constraint </uml>
