This TechNote pertains to the direct one-way link from Ram Structural System into Ram Elements. For information about using ISM to synchronize products, see Integrated Structural Modeling.
Foremost, RAM Structural System divides the model in gravity members and lateral load resisting members. In RAM Frame, gravity members transmit only vertical reactions to the supporting lateral members and provide brace points). They do not get considered further in the RAM Frame analysis. In Ram Elements (Ram Advanse) there is no separation of gravity and lateral members and the behavior of the structure is analyzed all together (when the full model is imported).
These differences can significantly affect the results, even for a model that is imported into RAM Elements (Advanse) from RAM Structural System
