STAAD.Pro CONNECT Edition V22 Update 8) vs STAAD Pro V8i


We performed a steel structure analysis for seismic qualification. The analysis is carried out in STAAD Pro connection edition and STAAD Pro V8i edition. The structural member's design checks are done as per IS 800 : (Limit state design)

Issue is :
On the failure beams check, we notice the difference in utilization factor reported in results output in both versions of STAAD.
Say in one beam, in STAAD Pro connection edition: utilization factor of the failed beam is 1.004
but in STAAD Pro V8i edition: the utilization factor of the same failed beam is 1.512

Kindly clarify why the results are different in different versions of STAAD.
