Claddings - Local axes planar loads on contour

[rigid_joint]

I'm facing the following strange problem.

When I choose to insert a "planar load on contour" on a cladding, the local coordinate system option seems that it's not working.

It always inserts loads with the global direction.

Any ideas why is that happening?

[Rafacascudo · Accepted solution]

Contour loads on local coordinate system require structure model to be already run to be displayed correctly

Hello!  I can't quite understand this.

You mean that I run the model and then I insert the loads?

Because I tried that and nothing happens. Loads are still loooking at the global direction.

I found this. it's all about a visual bug?

Hello!

I tried this but nothing really happens at all. As far as it's just a vision flaw/bug, but loads are really in local axes, I hope that there is not an analysis problem.

ok, I think I finally got it! If I have any more questions, I will return. Thank you!

Hello 

I have the same problem than you rigid_joint, how did you do to set the load according to the z axis of the local system??

Tank you

See post 2 and 4 in this thread

hello Rafal,

If I understand the capture of 2 and 4 posts shows that from a load define in local axis of the bar, you generated component load in the global axis.

What I need is to set my load in the local axis of my cladding (wind load on angled roof) so I choose "local" in the definition of my load but the direction of it seems to stay in the global coordinate system. This is wrong cause it will generate load and moment in my bar that are not real.

thank you

See post 4 - it is related to panels \ claddings

Yes but it shows how to set a devide a local load into a global load?

I wish to do the reverse.

[Rafal.Gaweda]

Sorry I do not understand.
You may have loads:
Global
Global Projected
Local

I am sorry, I should not have explained correctly what I mean.

Concretely, I calculated and applied manually my wind loads.

For the angled roof, the value I calculate is orientated along the Z axis of my cladding (see local coordinate system of my cladding as attached)

So when I apply it I put my load, for example Pz=30daN/m², i choose the contour, the cladding concerned and define the coordinate system as local

but graphically, the load stay in the global system

see capture attached

I hope I was more clear and thank you for your time

You did not understand post 4.
Correct local load display on panels \ claddings is done after Model Generation \ Calculations with "Forces Generated Automatically" marked

Your load definition is correct.

[Anonymous]

OK, sorry.
It still doesn't work when I follow the step of the post 4.
But I see I have an error "loads not correctly ditributed on objects or elements"

should comes from there...

A suggestion about that?

thank you again for your help

For claddings forces are generated in GCS on bars (in your case, in Z and Y directions) to get as a result the resultant perpendicular to cladding plane
