The RAM Concrete Wall module makes use of load combinations in design.

The combined loads represent the demand side of the design calculations. At least one load combination must be defined before the design process can be executed. Load combinations can be generated: automatically (Generated Combinations), entered manually by the engineer (User Defined), or imported from RAM Frame (Advanced Load Combinations). Generated and User defined combos superimpose load case results.

The load cases (Dead, Live, Wind, Seismic, etc.) that are used in the load combination terms of generated or user defined combos in the RAM Concrete Wall module represent the load cases that were analyzed in the RAM Frame module. Therefore, the load cases available for combining in the Generated and User defined Load Combinations dialog in the RAM Concrete Wall module are the same as the load cases that were created and analyzed in the most recent RAM Frame analysis.

On the other hand, the load combinations available in the Advanced Load Combinations dialog in RAM Concrete Wall are those that were analyzed in RAM Frame Load Combinations mode in an advanced analysis.

Changing the defined Load Combinations (e.g., regenerating the combinations, adding or removing combinations, etc) once a design has been performed will cause the reinforcing for all non-frozen Wall Panels to be cleared.

A dialog corresponding to each method of creating Load Combinations is available. The design process considers the load combinations created from all methods. Each method of load combing is discussed below.
