The RAM Frame Drift Control module requires the application of fictitious load(s) in the direction of the displacement under investigation. Such fictitious loads are grouped in the RAM Structural System as "Virtual Load" cases. The virtual loads are entered by specifying their respective magnitude, direction, and point of application.

Properties of the virtual loads are entered in the Virtual Load Case Story Forces dialog.

• Story - Indicates the level at which the force acts.
• Diaph. # - Indicates the diaphragm at which the force acts.
• Force - Indicates the magnitude of the force.
• deg - Specifies the direction of the force measured in degrees. 0 indicates a force acting along the X-Axis. 90 indicates a force acting along the Y-Axis.
• X - The X-Coordinate where the force acts.
• Y - The Y-Coordinate where the force acts.
