When I analyze a quiet complex spatial structure, error information warn that: the direction of the beam element is
not correct.

From abaqus document 26.3.4 I know we can
nominate the direction of beam element by adding additional node.It is clear
that this node should be off the axis of the element,any additional constrians?

Hi, everyone:

I am using ABAQUS to do my final dissertation:nonlinear analysis of steel members.

I want to apply UNIFORMLY DISTRIBUTED LOAD to the middle height of the web, I splited the web into top and bottom parts,but nomatter I use 'LINE LOAD' OR 'SHELL  edge LOAD' ,it does not work at all.

Thank you so much in advance, any opinion is welcome.

Hi, everyone:

When I simulated the beam with shell element, first I define reference points at both end of the beam and assign 'RIGID BODY/PIN OR TIE' to  nodes at the edge,after that I applied bending moments and boundary conditions to both reference points.  But after I finished the buckling analysis, the result is not reasonable,the eigen value is about two times the the value I expected.
