Table Tool in midas Gen offers a variety of powerful built-in functions. Refer to Usage of Table Tool for detail directions.

From the Main Menu select Results > Tables > Result Tables > Story > Story Drift (Time History Analysis)

From Records Activation Dialog, select the time history load cases for which story drifts will be calculated.

Refer to Usage of Table Tool and check the following data:

Drift(X): Story drift in GCS X-direction

If Consider signs in load combination type of envelope "All" option is checked in Tools > Preference > Results, the values are produced with signs instead of the absolute maximum values (The option is unchecked by default).
