When running the STAAD, the result shows everything is right,. Structure is stable, no warning. Displacements are limited. BUT, I get some funny numbers for rotational displacement e.g. 533 degree & sometimes more.
I checked releases. I believe they are correct.
any body can help me out kindly ??
Please check if the abnormal rotational displacement that you are getting is in the Mx direction and advise.
I should say mostly yes, but not necessarily.
The model is an industrial steel structure.
It happens on the top of the columns, which is rotational displacement around local x of columns.

It appears to me that you have relesed Mx at both the ends of the member and also blocked the warning message otherwise you would have been cautioned. Please check and advise.
No, I think that's not the case.
The column is not released at all.
The support is "Fixed but released: MX & MZ"
Thank you
There is some modelling error in your file. You may post the file for verification.
I attached the file ............ Please kindly review. Thank you
I tried my best to locate the abnormally high rotation in the post processing. I did not get. Will you please state as to for which load case and node no. you are getting high rotational displacement? I got normal output.
Load case 3, node # 14 >> rY 354 deg
Load case 205, node # 88
Load case 175, node # 168
there are more examples
The file that you have posted has max 74 nodes and numbered 74. Hence there is no question of node no.88 and 168. You might be seeing something else in output file.
really sorry ...........I am working on two models at the same time.
here are correct numbers:
Laod case 3 >> node 28, rY 293 deg
& node 20, rY 288 deg
Load case 175 >> node 28
Lad case 173 >> node 10
