When trying to calculate a result combination, I receive the "Warning No. 30014 - Unacceptable addition of load cases in reculs combination! The result combination includes load cases or load combination with result according to the second-order theory with nonlinear relations and thus, they cannot be added [...]". What does this mean exactly?
- LC/S + LC/S
- factor * LC/S or factor * LC/S
Detailed explanation is possible on the second definition variant, for example: A load combination was calculated according to the second-order analysis. Results show a nonlinear relation, which should not involve doubled axial force with doubled moment at the same time, for example. Now, if you add a factor to the lod combination results, it multiplies each internal force. This conflict (nonlinear calculation of results and the subsequent linear multiplicartion) causes the warning appears.
