In addition to the member design provisions of each design code, building structures are also required to meet certain drift limitations. The Drift Control Module provides you with a means to see how each of the lateral members contributes to the resistance of that drift. For the Tutorial, drift at the Roof Level in the X and Y directions is the primary concern. In this section you will define a virtual load case in both directions, pair those load cases with the governing seismic load cases and review the results in order to determine which members provide the greatest resistance to that drift. You will also determine how to improve the overall structural performance.

This is an optional module and is not included with the RAM Frame basic module. In order to perform this section of the Tutorial you must have the RAM Frame - Drift control Module installed and the hardware lock programmed for that module. You can skip this section otherwise.
