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_Constrait objects. To construct a load pattern and populate it, the following command is used:



The command to generate a multi-support excitation contains in { } the commands to generate all the ground motions and the single-point constraints in the pattern. The command is as follows:

pattern Plain $patternTag $tsTag {
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
the tag of the time series to be used in the load pattern
load... command to nodal load
eleLoad ... command to generate elemental load
sp ... command to generate single-point constraint
