When displaying the deformations of LC1, the maximum is 10 mm. If you look at the deformations of CO1 (defined as 1.0 * LC1), there is a larger deformation as a result. How is this possible?

Answer

By default, load combinations are calculated according to the second-order analysis, load cases according to the linear static analysis. It is possible that the stiffness is reduced by a standard-dependent partial safety factor in the calculation according to the second-order analysis, which has the corresponding effect on deformations.

In order to obtain the same results in the load case and in the load combination, it is necessary for this case to regulate the consideration of stiffness factors in a uniform manner (see figure).
