Bracing is not getting connected to Beam

Post by pradeep0410 » 14 Nov 2019, 15:52

Version-2018. I am using inelastic force braced frame element as beam and inelastic truss element as bracing. I want to give pin connection at middle of beam, to that I want to connect bracing. When I use to connect like that it is showing zero diagonal error. :cry:

The warning does not mean that the model is wrong. It is just a warning.
If you use the Skyline solver that can accommodate for zero diagonals in the stiffness matrix, the analysis should be ok (provided of course that the model is correct and stable).
