Dear STKO Team，
I want to get the right bending moment at the node of the first floor (only 2e-05 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 non-zero 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. )

Re: How can I get the bending moment of the first floor?
If you are using Lobatto integration in columns, then the last gauss points are located exactly at the end-nodes, so it should be the same.
Are you sure the models (OpenSees and ETABS) are actually equal?
