Hello ARSA support

When I put a cladding at my construction it seems to be wrong load distribution.

See attached file.

Everything looks OK, but the beam 24 and 17 (in the lower part)

No load distributes to (41 42 43) and (11 12 25)?

Try to display loads generated automatically to verify the actual generation of loads.

Hello Artur

See attached PNG.

It shows that the loads don´t distributes to all of the beams.

Attach this model please.

Hello Artur

Here is the model.

See the two Lineloads with PZ-info (-5.7 & -8.2) outside the model at LoadCase "Nyttig Kat. C3"

They should be approx the same.(3,0 x 1,9 = 5,7)

This is going to be a stupid question but why want to have load applied to the edge beams when you set them as being ignored during load distribution?

Hello Artur, that´s not a stupid question!

The beam is in fact a "wall", but I dident manage to set it like a wall. I got problem with the releases for the beams. And that is because I haven´t manage to fully understand the releases yet. I guess I was trying a lot of things before I gave up the walls.

Actually, I have put so much time to understand Robot, which is a very good program, but unfortunately without a good documentation.

I will try to investigate my problems better next time.

Thank´s Artur

(Do you have somthing good to read/see about releases - Please send it to me)

In such case you could either define a vertical panel or just supports instead of these beams.

I got problem with the releases for the beams.

This should not be that difficult. You can apply them only to beam's ends. By default all is fixed meaning you have transfer of bending as well as shear and axial forces. If you want to have one of these internal forces not to be transferred to other elements you define release marking the corresponding check box e.g. RY which means there is no MY bending moment transfer (pinned connection).
