I'm using RAM SS to design a building where we have raised slabs modeled due to a bridge framing into the building. I'm wondering if there are any special requirements in order to have RAM use the main floor diaphragms to calculate the tributary heights for the wind load distribution. I've created a sketch showing how I'd like RAM to consider the floor to floor heights. Thanks in advance for any advice/tips for modeling this!

Check out our wiki on wind loads. https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/2052/ram-frame---wind-loads-faq We always assume a level has both windward and leeward exposure, so it's not quite correct for partial level structures.
Hi Seth, thank you very much for the response! Is there a workaround for this? Would going into the exposure menu and turning the intermediate levels off be appropriate for ensuring that the main building levels are used in determining the tributary heights?
As noted in the wiki, User Defined Story forces are the best work around.
