Wall panel cuts with seismic loads

[Anonymous]

Hello,

I have 10 combinations of loads, 8 of them has seismic loads. When I make a panel cut on any wall it only show results for the combinations that does not have seismic loads. I am trying to get axial forces and moments in specific sections of the walls.

I'll apreciate some help,

Thanks

So select the correct one , or I missed something.

the thing is when I select any combination that doesn't have seismic loads it shows diagrams and results, for example in comb 1 and 2, but in comb 3, 4,... etc that has seismic does not show any results, I have attached some images maybe that explains better

Do you need more info? Am i asking something very basic? I am learnig to use Robot and I've been searching over the web and this forum about this "little thing" and nothing... the tutorials and the manual about Robot are very few and basic in comparisong to SAP, so... harder to learn...

Thanks for the links, I already have those manuals and the videos

Turn off saving cqc results only

Thank you but now it gets stuck in static analysis, please see attached picture

[Rafal.Gaweda]

It takes 500 sec to calcaulate your model with 142 modes, then a few minutes to calculate and save cqc results.

Thank you very much,  I see you made changes to the mesh and now it takes less than 10 min to run, before that it was almost 2 hours, so I guess I was using a complex meshing that was not necesary.

Sorry to continue bother you but I want to know so I won`t make the same mistakes again, a few questions:

I see you used Multi-theaded solver could you explain me why?

When I run the verification analysis I get a few warnings (please see attached imaged), since you run the model are those warnings not serious? Should I try correcting them? If so what about this warning: “the load has not been distributed….” I checked those panels and it seems ok, could you explain me what’s happening?

The fastest solver we have in Robot.

"Error object meshing" in your model:

remove these degenerated panels

[Rafal.Gaweda]

"Element not assinged to any story" in this model:

delete the panels from post above, then run Geometry \ Stories \ Assign Geometrically for Whole structure

Warning about loads on your model : bar force load should be used without node generated

Thank you very much for your help, I really appreciate it. Waiting for that tutorial you mentioned earlier, I don't like to bother you, just only as a last resort.
