How can I set as quickly as possible that the load combinations generated by the program are calculated according to e.g. first order theory?


In the 'Load Cases and Combinations' window, you can specify in the bottom right of the 'Combination Expressions' tab which calculation type should be used as the basis for the generated load combinations. Presetting of load cases refers to the linear calculation according to first order theory, presetting of load combinations to the nonlinear calculation according to second order theory.

Thus, you can quickly determine whether the load case or the load combination is calculated according to I., II., or III. order theory. Select the option of post-critical analysis to carry out a stability analysis according to the large deformation analysis under consideration of the post-critical failure of the entire structure.

If the model includes cable members, the calculation according to the large deformation analysis is preset in all cases.
