Can someone help me to rectify it, please? As per my understanding releases in staad are local and not global so I have released MY and MZ in the middleen-USTelligent Community 12https://communities.bentley.com/thread/480146?ContentTypeID=1Thu, 06 Sep 2018 18:14:28 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:adb79adc-1931-40f0-9db0-0c0957bba276Sye<p>Your understanding of the releases is correct.</p> <p>The instabilities at the nodes&nbsp;are however reported with respect to global directions. You are getting these warnings at nodes 5 and 6&nbsp;as there&nbsp;are no rotational restraints about global X at these nodes because&nbsp;the local MZ moments at the&nbsp;start and end of the angle member&nbsp;are fully released and&nbsp;supports at the ends of the&nbsp;longer beams are PINNED. To take care of the instability warning you&nbsp;may&nbsp;change the full release for the angle member to partial release. A modified file is attached for your reference.</p> <p><a href="https://communities.bentley.com/cfs-file/__key/communityserver-discussions-components-files/5932/Partial_5F00_Release.STD">communities.bentley.com/.../Partial_5F00_Release.STD</a></p><div style="clear:both;"></div>
