Hi everyone, I have some matters with 1D element.

In beam structure, connecting locations by welding include shape steels as channel and angle steel (nonsymmetrical section) . Absolutely, we shall model these steels into lines. Shall we create lines on shear center or neutral axis ? What case is suitable for behavior in real-life?

Thank you everyone

Best Regards.

    Depend on your real structure: forces are transfered via welds, sum of these forces called total force and I think beam's node should be at position of the total force.

    Thank you Mr. Tinh

    Assuming I create line at shear center and connect lines together by RBE2.  That's alright ?

    Best regards

    Please refer to CBEAM card info in Optistruct Reference Help, you could need to set offset values.
