How do I best model two parallel welded bars?


There are different possibilities:

1) Connection of the two bars by means of rigid bars at certain intervals:

  • Division of the bars at certain intervals (right-click on corresponding bars -> "Share rod"
  • Connection of the newly created nodes by means of rigid rods
2) Disassembly of a rod into a surface (only possible in RFEM):

  • Right click on one of the bars -> "Disassemble rod into surfaces"
  • Movement of the other rod into a plane of the newly created surfaces so that the line of the displaced rod is integrated into the corresponding surface (control: Dialog window "Edit surface" -> Register "Integrated")
  • Defining a column eccentricity so that the original situation is restored ("Edit staff" -> "Settings" tab -> "New column eccentricity" -> here practical: "Relative offset")
  • If the rod, which has now been broken down into surfaces, should be dimensioned in an additional module, then a result bar can simply be defined here
3) Using the DUENQ single program to model and dimension individual cross sections
