Hello
I'm in the process of performing RDM calculations on a framework. On this framework there are parallel beams screwed together.

(in reality my framework is much more complex).
How to simulate these 2 integral beams in solidworks simulation, one of which is loaded?

I use beam elements so I can't add a connector. I tried to add solidarity contacts between assemblies or components but it doesn't work.
The only solution I see is to use volume elements (not great because of the complexity)
Subsidiary questions:
Why in the drawing of the results, the plate "wraps on the tube" when it is a square tube (I even checked render beam profiles in Mesh)?

Is it possible to hide bodies in the drawing of the results?

Hello
It is not possible to combine the 2 beams?

It's up to you to position your load on the 2 square tube section
to take the resitance of these 2 tubes
who + is, they must be supportive and not independent
It's not because you're going to multiply the square tubes over the width that you're going to increase the mass to support
it is better to multiply on the height

Look at this link

By splitting the profiles at the bolt connection. The profile will have 3 knots.

Hello
In beam mode, the connections are only made on the nodes of the beams.
So as @opie27 says, you either have to have an extra knot by splitting the profiles at the bolts or you have to calculate in volume!

Thank you for your answers
My problem is only a modeling problem, how to make two parallel beam elements together, one of which is loaded, without trying to find out if it is the best design, thanks anyway for the pdf.
I'll try by splitting the tubes...
I succeeded by splitting the tubes. On the other hand I had to modify the connections by treating as a connection a clearance of less than 45mm (I use 40x40 tube) and I had to modify the length of one of the 2 tubes so that it protrudes more than 45mm.
