Using Self-Equilibrium Analyses

Setting the Loading Analysis Type

To have RAM Concept analyze a loading using a self-equilibrium analysis, the loading's analysis type must be changed to "Lateral SE" (lateral self equilibrium). The loading analysis type can be changed in the loading window. See "Changing Analysis" in Chapter 10, "Specifying Loadings".

Note: The term" Lateral SE" is used instead of "Self Equilibrium" to remind users that this analysis type is primarily intended for lateral loadings.

Defining the Loads

There is no limit to the type or quantity of loads that can be applied in a self-equilibrium loading. However, the loads applied must be nearly in self-equilibrium. If the loads are out of equilibrium RAM Concept will apply restraints to the slab to ensure that equilibrium can be maintained. The restraint reactions can be viewed in the Calc Log.

Note: See "Importing a database" in of Chapter 14, "Importing a Database from the RAM Structural System" for information on how to automatically import self-equilibrium lateral loads.

Note: Mat/Raft foundations are typically not well suited for self-equilibrium analyses as the soil reactions are not known before the analysis.
