Hello, I am modeling a foundation that is 7 feet below top of slab and have a BRB frame above. I've modeled concrete pedestals (set as a lateral element) and a concrete wall in between (set as a gravity element) to get some extra dead load on it.
Adding the concrete wall seemed to help quite a bit on reducing the footing size. I am assuming this is because the wall helps to distribute the offset horizontal reaction from the brace?? I just want to make sure I am modeling everything correctly for sizing the foundation. Do you have any guidance or see any issues with how it is modeled?? Should the wall be modeled as a lateral element instead?? How does RAM foundation treat the wall? I want to make sure Please see the below image for reference.
