Dear All,
Greetings to you.
It is observed that for AISC LRFD design which i am performing, the result output provided in GUI and the ones provided in summary report as well as detailed report are entirely different.
Initially i have strength and serviceability envelopes. However, as per a previous post in this forum, i have removed the envelope for simplicity. Still i am facing this issue.
Can anyone explain the reason behind the different results. Details are provided below.
Best Regards,
PNP

Gentle reminder. Request you to advise on the query. Thanks a lo in advance.
Please attach the related STAAD.Pro model for the investigation.
Hi,
Please find attached model. It has changed a bit. However, the issue highlighted in the above query still persists.
Model 09042020_2_1.txt
This is very strange. I am not seeing this behavior at my end ( screenshot below).
I would suggest doing the following
Ensure that you are using STAAD.Pro CONNECT Edition ver 22.03.00.28
If you are and still facing the issue, create a new folder and copy ONLY the .std file into it. Use file explorer to copy the file and NOT the Save As from within STAAD.Pro.
Rerun the analysis and check the design
