Design Loads

The design loads used in the RAM Concrete Wall module are taken from the RAM Frame module. Thus, a RAM Frame analysis must be performed prior to designing wall reinforcing in the RAM Concrete Wall module. The load cases analyzed in the most recent RAM Frame analysis will be available for use in the Load Combination menu. The load cases are combined according to the automatically generated or user-defined load combinations in the Load Combinations menu. See the Load Combination Generator manual for additional information.

You should be aware of a special consideration regarding live load reduction. In RAM Frame, the portion of the live load acting on a wall that is delivered from two-way slabs is not included in the reducible area for the live load reduction calculation. Thus, absent any other action, the live load forces in walls that support two-way slabs will be larger than if all tributary area for the wall had been considered in the live load reduction calculation. To overcome this, you may directly assign a live load reduction factor to a member in RAM Modeler, which will then override the value automatically calculated by Concrete Analysis.

You should also be aware that, since RAM Frame loads are necessary to design a wall, Walls assigned as "Gravity" in RAM Modeler will not be available for design in the RAM Concrete Wall Design module.
