https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/184278/column-and-wall-rigid-zoneHi, I am reading a post about modeling in RAM Concept. One of the questions mentioned rigid zones at columns and walls. See the snapshot below: My question is what stiffness factors one should use for these rigid zones: Thank you.en-USTelligent Community 12https://communities.bentley.com/thread/539699?ContentTypeID=1Thu, 22 Aug 2019 14:50:40 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:99d4b5b2-d17c-43fb-8608-a603a7a7763dSeth Guthrie<p>If you are thickening the slab to make the joint stiffer then you can Leave K at 1. Increasing K would be another approach to achieve the same thing. Moment stiffness is related to E but to t cubed, so the increasing K vs t is&nbsp;not linear.&nbsp;</p><div style="clear:both;"></div>
