https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/168878/staad---simple-beam---excessive-deflectionI am playing around with a simple beam analysis in STAAD (version 20.07.11.82) with only member dead load case (1.0 gravity load factor). I initially had it modeled as a 2-member beam fixed at a midspan joint. Then I changed it to a single member.

That was it.</p> <p>I even have a note on my section properties worksheet to check the STAAD orientation, but I decided to be stupid instead.</p> <p>Thanks!</p><div style="clear:both;"></div>https://communities.bentley.com/thread/484407?ContentTypeID=1Thu, 04 Oct 2018 18:43:09 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:e1707605-f011-4acd-9b9a-7e8429824cb0Abhisek M<p>Please check the sectional properties you have entered for the member. Probably the inertia &amp; section modulus values in both axis got exchanged. If you enter beta angle 90 for that member you will be able to match the values with your hand calculation. Please check and let me know if it is the case.</p><div style="clear:both;"></div>
