Load Distribution

[davidgholmes]

Think this should be quite a simple problem to solve!

I have defined surfaces around the building so I can apply a wind load to building but when I try to define how the load is distributed I don't seem to be able to do it as shown in the help section (http://docs.autodesk.com/RSA/2012/ENU/filesROBOT/GUID-2F6BADFE-F90B-46AA-97F8-227926DB9A7-306.htm)

as there are no two-way or one-way options and the new button is greyed out, as shown in attached screen shot. I think this is stopping any loads being applied correctly to the structure.

Am I missing something very simple or need to install anything?

Thanks

For walls (which are panels) you need to make this cjange by assigning the appriopriate calculation model to them.

Sorry, maybe I didn't explain myself very well before, but I was trying to use cladding instead of walls as I didn't want these contributing anything to the structural strength of the building.

I defined cladding all the way around the building but when I apply a load it doesn't seem to go into the floors or walls, so I thought it might be something to do with the load distribution pattern.

Do I need to define the envelope as walls to make sure the wind load is transferred back into the floors, shear walls etc?

Thanks again

If the walls and floors are defined as perpendicular to the claddings with their edges being in the claddings planes then the load should be transferred.

Thanks,

Looks like I just made a simple mistake of defining the cladding at the edge of the column, instead of the node so the load had no way to transfer into the structure.

I'm still slightly puzzled why the cladding properties box wasn't complete, but looks like I have got around that anyway...
