I&#39;m just wondering if RAM SS can handle stuff like this? Any experienced? Thank you.en-USTelligent Community 12https://communities.bentley.com/thread/381377?ContentTypeID=1Tue, 30 Aug 2016 02:15:34 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:9f233f3b-f3a8-4617-a274-dcad1d4088fbSeth Guthrie<p>I see people modeling some complex roofs in RAM SS from time to time and now that we have stub cantilevers (beams connected to only one support) there is a lot of possibilities. &nbsp;My cautions are are mostly that the diaphragm should probably be flexible as you don&#39;t want a rigid diaphragm inhibiting the thrust of a sloped roof. Also be sure to model each slope of the &nbsp;deck with a separate polygon and remember that wind load generation is based on the original story height only.
