How to get separate compression & tension forces for panel reduced forces.

[Anonymous]

What is the best way to extract the panel forces in a case as below if I want to know the total compression force and the total tension force separately? 

The only way I can think of is to split the panel in the middle. The downside of this is that the neutral axis will not match that of the diagram (but hopefully it will be close enough). There are many load combinations so I cannot split it at the neutral axis for each load combination.

Maybe you can select only the FE in tension (or compression ) and mark" display atributes only for selected objects" on view/display .
Other way would be set the cut lenght precisely according to the tension or compression region

Hi @Rafacascudo, thanks both those work!

It would be nice if Robot calculated this automatically, eg

• Total integral value
• Positive integral value only
• Negative integral value only

Just an idea:

if you have nodes at the position of the panel cut. You can get results at that FE nodes thru API and have the diagram in excel for all the combinations. There are several posts and tools to help with this task in the forum.

Then you can do whatever you need there. The discretization of the diagram will, of course, depend on the nodes distance that you choose.
