Question

What is the best way to model two welded members lying parallel to each other?

Answer

The following options are available for modeling two welded members lying parallel to each other (Figure 1):


1) Connection of the two members by means of rigid members at specific spacings:

  • Division of the members at certain distances: Right -click on the corresponding members → "Divide member"
  • Connection of the newly created nodes by means of rigid members


2) Decomposition of a member into a surface (only possible in RFEM):

  • Right -click one of the members → "Divide member into surfaces"
  • Displacement of the other member into a plane of the newly created surfaces so that the line of the displaced member is integrated into the corresponding surface (check: Dialog Box "Edit Surface" → Tab "Integrated")
  • Defining a member eccentricity so that the original position is restored ("Edit Member" → "Settings" tab → "New Member Eccentricity" → here practically: "Relative offset")
  • If the member, which has now been divided into surfaces, is designed in an add -on module, you can simply define a result member here


3) Use the single program SHAPE-THIN to model and design individual cross-sections
