The forces on gravity members supported by foundations can be taken from either RAM Concrete Analysis or RAM Steel. Use the options in the Criteria - Gravity Forces dialog box to indicate which program will be the source of the forces on gravity members.

To obtain forces from RAM Concrete, an analysis must be successfully completed in the RAM Concrete Analysis module. If a license is not available for RAM Concrete, the option is still available in Criteria - Gravity Forces but the gravity forces will not be available.

The current selection indicating where forces on gravity members originate is displayed in the status bar at the bottom of the main window.

Note that irrespective of the selected option, gravity forces are NOT carried down brace members (which are lateral members in RAM Structural System). All gravity forces on lateral members (walls, braces and columns) are taken from the RAM Frame Analysis results and considered in the Foundation Design.
