Modifying input time-history characteristics

Users can make use of the Change Time-step and Scale Accelerogram commands, available from the Tools menu, through the respective toolbar buttons (indicated above) or from the corresponding popup menu (available when the user right-clicks on top of the time-series tables) to change the time-step of the accelerogram (linear interpolation is employed) and/or to scale it up or down by a constant factor, respectively.

Users can also take advantage of the Paste command to add additional acceleration values to the loaded time-history. These added values are appended at the end of the existing accelerogram.
