How can i fix this error "check of lateral-torsional bucklying is not available because z-axis is major" for the section created RSECTION (rotate the section do not work), thanks

Hi, @juli960916! LTB is not checked for the section's weak axis (z-axis). Therefore, if Iz > Iy, this is a limitation of the standards and software. LTB is only calculated for the section's strong axis. You'll need to manually check this stability failure mode and further have the option to turn off this warning in the program. If Iy>Iz and you are still getting this warning, the section can simply be rotated in RSECTION so that the y-axis is considered the strong axis. For any further questions, please email your questions and model to info@dlubal.com.

The RFEM 6 is way difficult then the RFEM 5 :), IN RFEM 5 my member in ALU is passing in normal design by closing stability analysis otherwise there is an error 1022 (RFEM 5), but when i RUN RF FE LTB the member check passes. For RFEM 6 I am unable to find a manual method to run the RF FE LTB and notiably when i run the member analysis it is failing in stability, first thing i want to know how to close stability check in RFEM 6, lastly how to remove warning WA3002.00 saying Asymmetric sections not valid for LTB design and Asymmetric sections are not valid for combined stability design.

Hi, @ghilmandilshad9495! If you are not interested in LTB design checks in the RFEM 6 Aluminum Design add-on, you can simply uncheck the checkbox for LTB under the member's "Effective Length" input. There is not an equivalent RF-FE LTB add-on in RFEM 6 as all LTB checks are within the specific Design add-ons. If you still have further questions, feel free to email us your model to info@dlubal.com.
