Markus Baumgärtel Results RFEM RSTAB Structural Analysis & Design

In my model, I get different results than with a manual calculation and other software.

What could be the reason?

Answer

By default, the shear stiffenings of members are activated in the program (see Figure 1). The calculation type and defined stiffness factors (see Figure 2) also affect the calculation. However, the parameters mentioned above are often neglected in the manual calculation, which of course contributes to a result difference. If these functions are deactivated, the results are usually identical with the manual calculation.
