In a time history analysis, how do I get the Amplitude of Vibration of the beam?

You can get this from the joint displacement values for the time history load case. You can specify the command PRINT JOINT DISPLACEMENTS in your input file, in which case the values will be reported in the output file. These values can also be seen from the node displacement table in the post-processing mode.

You can also get a history of the displacements of the nodes in the structure graphically. In the Postprocessing workflow, select Displacement from within Layouts > Dynamic from the ribbon menu. Then click on any of the nodes in the model, and the history of X, Y and Z translations will be shown in a graph on the right hand side of the screen.
