Hi, I'm trying to analyze the frame truss combination attached below in 2-D. The problem is that when I try to redo the analysis to verify my results, I get different deformation modes, and values of the analysis as shown in the figures below even though I double-check everything to not make a wrong assignment of a certain value, section, profile, or orientation. I feel the problem is that I draw frame truss combination as only one object while sketching as attached. So, I tried to draw the trusses as part 1, then the beams as part 2, and assemble them in 2-d, but the program displays an error saying there are nodes open while preforming the analysis, which means there should be some sort of constraint or boundary condition between the truss nodes and the beam nodes during assembly. So, how can I solve that or how can I add constraints on these nodes in 2-D? Any suggestions will be highly appreciated. Note that I need the analysis to be conducted in 2-D using deformable wire elements.
