When trying to calculate a member structure, I get Error Message 1677 "Member No. 75: Invalid effective length factors."

Q: When trying to calculate a member structure, I get Error Message 1677 "Member No. 75: Invalid effective length factors.&quot;

In RFEM 5 and RSTAB 8, it is possible to define the effective length factors that are then applied in the add-on modules.If this message appears, the entry of the factors in an old version has been set to 0. Due to this incomplete member definition, the calculation in the main program is not possible. To fix this, enter a value &gt; 0.If the effective length factors are still not relevant for the design, you can select the entire model and then open the "Edit Member" dialog box by double-clicking the member. Then, set the factors to the default value of 1.0 in the "Effective Lengths" tab.
