Dear STKO Team，
I want to get the right bending moment at the node of the first floor (only 2e05 N), but I can only get the base bending moment( about 400000 N), how can I solve it? Thank you!
How can I get the bending moment of the first floor?

Re: How can I get the bending moment of the first floor?
It's because you are extracting it as a reaction force. Of course the reaction will be nonzero only at fixed nodes. At the floor level you could try to export (from gauss points) the section.force result (pay attention: it's in local coordinates)
Re: How can I get the bending moment of the first floor?
Thanks for the response, but is there any way to obtain the moment at nodes? The moment from Gauss points are still a little bit different from column moments in ETABS. Thanks a lot. (Moments and Rotations at Gauss points have already correspond with hinges in ETABS. )

If you are using Lobatto integration in columns, then the last gauss points are located exactly at the endnodes, so it should be the same.
Are you sure the models (OpenSees and ETABS) are actually equal?
