While there is no timeSeries command in the language, a number of commands take as the argument a list of items which defines the TimeSeries object to be constructed as part of the command, such as the LoadPattern and groundMotion objects.
Time series act differently depending on what type of object they are applied to:
LoadPattern object: |
|
|
Load factors are applied to the loads and constraints |
groundMotion object: |
|
|
Load factors are applied at the DOF in a ground motion |
The type of TimeSeries objects available are presented in this chapter.
NOTE: The TimeSeries objects are handled by the Tcl interpreter as lists. Therefore, they can be defined a-priori within quotes "" and given a variable name. EXAMPLE:
set Gaccel "Series -dt $dt -filePath $outFile -factor $GMfatt"; # time series information
pattern UniformExcitation 2 1 -accel $Gaccel; # create uniform excitation
