If the third option is selected, forces on steel and 'other' columns will come from RAM Steel. See Section 3.4.1 for more information.

Forces on concrete columns and all walls will come from RAM Concrete Analysis. See Section 3.4.2 for more information.

It is important to note that, if there is a diaphragm in the model that has two-way slab action, the Criteria - Forces option is automatically changed to this option and the option to get forces from RAM Steel is made unavailable. This is because RAM Steel cannot distribute loads from a two-way deck.

In the rare case where a two-way deck is modeled on steel members, the foundations that support these steel members are not designable. To design these foundations, gravity forces must be taken from RAM Concrete.
