Markus Baumgärtel Results RFEM RSTAB

If one can show the deformations of LF1 the maximum is z. B. 10mm. If you then look at the deformations of the LK1 (which includes the 1.0 x LF1), a larger deformation results at once. How can that be?

Answer

It should be noted that load combinations are calculated by theory according to 2nd order and load cases according to 1st order. Since the second-order theory is preset for load combinations, the stiffness is automatically reduced with the standard-dependent partial safety factor.

If one wants to obtain the same results in the load case and the load case combination, one would have to deactivate this reduction for this case (see Figure 1).
