Dear Sir,
Our Project Requirement: 600’ x 200’ x 43’ PEB Warehouse
We’ve taken a Model of 157’ x 200’ x 43’ for STAAD Analysis as a similitude model with EJ
For the last 45 days, our design engineers have been carrying out the design work of the following PEP structure, and we are continuously concentrating the Staad design and also fully focusing the standards according to the Indian codes alone.
We’ve tried 100+ STAAD Models But we couldn’t get the Desired Result in the Design.
We have tried and tested, all available cold form steel systems for this from Staad.pro.
We have tried purlins with different spacing like 1.2 meters and 1.5 meters.
But at no place, the design pass of the members received as we expected.
So, We are broken highly...
Can you please check and correct any of the two files we have attached herewith,
I have run the file in my system in version 22.11.00.156 and found the highlighted members as failed.
One thing I have noticed that thr purlins are not having any releases at ends and hence the are subjected to moments at the ends. Are you design moment connection for purlins? As a standard practice all purlins are designed as simply supported or continuous over spans. Also, some engineers do not model purlins in structure and design them manually using guidelines in some standard books or SP code.
However, please review the end conditions and check if any modification is required. Use of sag rod may help in this case if you are doing manual calculation. In STAAD you can adjust the Ly Lz values depending on sag rod arrangements.
Thanks, Mr.Abhisek
Kindly Attach the STAAD File which is corrected by you.
I have not made any changes in your model. I have only run the file you have uploaded here. You may change the file as per your practical requirement as stated above.
