By using the Loads generator the user should select the way to generate buckling loads:
- Nx: In case Permanent actions are defined in MatrixFrame®, the Loads generator offers the possibility to generate horizontal loads equal to the axial forces as result of the permanent actions. Internally the generator performs a LE-analysis based on the LC's permanent actions and converts the axial forces to horizontal loads. Of course this option is only possible in case LC with LC type Permanent actions is defined.
- qG: The alternative is to select the simple way, where self weight loads qG in horizontal direction are generated.
In both cases (Selection Nx or qG) 2 LC's with LC-type "Buckling length" are generated, for Asymmetric as well as Symmetric.
