After applying the out-of-plane pressures to shells in my RAM Elements model, how do I assign the loads to a load case? I want to make sure that it is not applying the pressures to the wrong load case and double counting lateral loads from my RAM SS model import.
You need to add the load cases first (Home menu - Loads - Add/Edit). Then select the desired load case in the lower right hand corner before applying the pressures, or other types of load instances. You can right click in the spreadsheet to copy or clear existing data if needed.
Thanks Seth. I am running into another issue with lateral pressures. I have stairwellsat the ends of the building that are being used as shear walls, I have applied these lateral pressures to the exposed exterior shear walls. These walls are unbraced full height. However, when I look at the moment diagram from the lateral pressures, the walls are being treateds as braced at each level. Is this a RAM import issue or can this be modified in RAM Elements. See the layout and diagrams below.
I assume you are you using the Masonry module in an integrated way (not stand-alone), and the walls are meshed to these elevations because of some story definitions in the RAM SS file.
Make sure there is no rigid diaphragm associated with the intermediate nodes of the wall in that case.

Thanks for the help Seth. How does RAM Elements account for the overturning at the ends of the masonry walls caused by in-plane shear? Is this possible in an imported model or would I need to create a standalone wall with flanges? I attempted to add vertical design strips to design the extra bars required to resist the couple force but it seemed to disconnect the horizontal reinforcement from the rest of the strips (causing it to fail).
