Exceptional load

During dimensioning the foundation combinations do not take into account exceptional load. When we highlighting a combination containing an exceptional load then we see the corresponding values of force for this combination, while they do not appear under the foundation drawing above.

Hi @Anonymous

I made simply check using model defined from scratch and my results seems to be reasonable

Could you please send your file

I have the same problem, and still dont know what to do, to solve it. I've tried everything but it's pointless.

Hi @michal.245

ACC loads are not teken into account while spread footing stability check in Robot Structural Analysis

But ACC combination after generation using auomatic combination tool can be changed in ULS combination and then will be used while footing stability check

Short description of combination update process

Generate automatic code combination with accidental combinations included using Manual Combination generate option.
Open Load > Combination table.
Go to Edit tab.
With right mouse button open Table column and check on Type of Combination, then OK.
Select all Accidental combinations.
With right Ctrl pressed select Combination type column.
With right mouse button select Fill Special.
Change selected combination type to ULS.
Accidental combinations, changed into ULS will be used for stability check in RC spread footing module
