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.
