Proper Way to Input Multiple Members between 2 nodes in Risa3D
(OP)
I'm curious if there is a way to design with multiple steel beams between two columns. In other words, I'd like to have two beams and two braces attached to one column. When I try, seems that one of my beam mebmers gets stressed way more than the other, even though loads are even and each beam member is attached to the same nodes.

This may be a good application for a three dimensional model that can capture more complex behaviour.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

If one is sitting on the other with no composite action, then place the two beams a small amount apart and add multiple rigid links between the two. That's how i'd do it, but others probably have more elegant ways.
