Question

In the "Edit Member" dialog box, there is the "Effective Lengths" tab. How does the modified effective length factor or the "Check exceeding of critical buckling load" option affect the calculation in RFEM?

Answer

The effective length factors that you can change in the "Effective Lengths" tab are not considered in the determination of internal forces in RFEM or RSTAB. These values are presettings for add-on modules used for performing stability analyses, for example RF-/STEEL EC3 or RF-/TIMBER Pro. The values will be considered in the modules only.

However, the "Check exceeding of critical buckling load" check box has an influence on the calculation: if the the critical load is reached, the member fails. In this case, the program shows a message about the instability.
