Markus Baumgärtel Results RFEM RSTAB

In my model, I get different results than with a manual and other software.
What could be the reason?

Answer

By default, the shear stiffnesses of the rods are activated in the program (see Figure 1). The calculation type and defined stiffness coefficients (see Figure 2) also influence the calculation. However, the above parameters are mostly neglected in the manual calculation, which of course contributes to a difference in results. If these functions are deactivated, the results usually agree with the manual calculation.
