I model the columns, support beams, pan joists (using the pan joist tool), and slab. I wanted to check my work so i did no apply any external loading, but entered the concrete design tab to check the self weight reactions. When I check the max moment on a joist, I am getting a number that is 2x the expected moment from self weight. I then deselected the slab self weight and got a number that was closer to the expected results, but still a couple k-ft smaller.&nbsp;</p> <p>I have never used RAM to model concrete before, is there a trick I am missing?</p> <p></p> <p>Thanks,</p> <p></p> <p>ANdrew&nbsp;</p><div style="clear:both;"></div>https://communities.bentley.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09Tue, 07 Jul 2020 01:07:42 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:c004da48-a086-414c-b278-3f432a6b61e2Ask a question in a forum.
