https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/240921/how-to-remove-ram-generated-diaphragm-nodal-forcesHi all, I am working with an industrial structure with Pseudo flexible diaphragm. I observed an unusual displacement at couple of places in the diaphragm due to nodal loads (RAM generated nodal loads). I tried disconnecting that node from diaphragmen-USTelligent Community 12https://communities.bentley.com/thread/750808?ContentTypeID=1Thu, 26 Jan 2023 21:24:03 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:7010fd4b-a89f-4353-9527-06e2c347443bUma Ramasamy<p>Assigning&nbsp;specific frame number for those braces helped.&nbsp;Thank you!&nbsp;</p><div style="clear:both;"></div>https://communities.bentley.com/thread/750806?ContentTypeID=1Thu, 26 Jan 2023 20:50:09 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:9c52f2e1-9326-47ed-8cf2-f6c499fac573Seth Guthrie<p>In a pseudo-flexible diaphragm analysis the program looks for any frame columns, braces or walls within the area of the diaphragm that are assigned a specific frame number, then assigns a nodal load based on the assigned percentage for that frame.&nbsp; If there are nodes at braces or columns that you don&#39;t want loaded, then you might have to assign those lateral members to a different frame number. Or you can always revert to user defined nodal loads (Modeler - Elevation view).
