Hello,

I am performing a seismic analysis on a steel moment resisting frame with reduced beam sections with Abaqus. I checked my model, everything seems fine. But then the analysis results are showing extremely high moments (in RBS) of the order of 1xE+09 while the probable moments in RBS are around 500 KNm. what could be the reason for this and how do I fix this?

Any suggestions would be appreciated.

Thanks!
