The gravity forces applied to foundations from supported walls will vary depending on the user’s selection in the Criteria > Forces menu.

If the user has selected Forces on Gravity Members From > RAM Steel , the gravity forces applied to the footing will be those calculated from the gravity wall load takedown performed in RAM Steel Beam (for more information on how the gravity wall load takedown is performed see the RAM Steel Technical Manual). The user should note the following aspects of this feature:

• All point and line loads acting on the supported wall are taken directly down onto the foundation without any "fanning" of the load.
• Point and line loads that act eccentric to the centerline of the wall contribute an applied moment to the footing equal to the load magnitude multiplied by the resultant distance of the point or line load relative to the wall centerline.

If the user has selected Forces on Gravity Members From > RAM Concrete , the gravity forces applied to the footing will be those calculated by the RAM Concrete Analysis module at the bottom of the supported wall.
