Define (Time History) Parameters dialog
Used to define time step, damping, and arrival times for time history loads.
Specify a solution time step to be used in the step-by-step integration of the uncoupled equations. The default value of Time Step is determined as explained in TR.31.4 Definition of Time History Load .
The following options are available for specifying damping:
Specify values of possible arrival times of the various dynamic load types. The arrival time is the time at which a load type begins to act at a joint (forcing function) or at the base of the structure (ground motion). The same load may have different arrival times for different joints and hence all these values must be specified here. The arrival times and time-force pairs for the load types are used to create the load vector needed for each time step of the analysis.
Adds the specified load details to the currently selected load case in the Load dialog and closes the dialog.
Closes the dialog without adding any load data.
