In all RAM Structural System modules, the gravity surface loads applied in the RAM Modeler are automatically distributed to the supporting beams and walls. All beams are assumed to be simple spans (no continuity between adjacent beams). The reactions from the beams are carried down the supporting columns and walls (through each level) and are available at the base of the structure to load the foundations. This gravity analysis does not consider the continuity of any of the beams, gravity or lateral, steel or other material.

The live load gravity forces from RAM Steel are broken up into upward acting (negative) and downward acting (positive) loads. For models where downward and upward acting live loads exist (from the back span of a cantilever beam for example), there will be separate positive and negative live load cases, and hence separate gravity reactions on the foundations. In RAM Frame, live loads are also broken into discrete negative and positive loads for the analysis. Refer to the RAM Frame Technical Manual for more information.
