Wooden beams lateral torsion buckling not calculated

Hi all,

 

I am working on a floors with wooden beams.

All beams are are being calculated with Robot default member type "poutre bois" = "wooden beam".

 

When calculation process is finished, Robot is showing message that lateral torsion buckling is not taken into account.
This is the situation with only 4 beams.

 

I have noticed in the calculation note that My moments are not taken into account only for these 4 beams.

At the same time, diagram for My show values.

 

Also, I have noticed that when section for these beams changes to smaller, problem disappears.

 

Link to the model:

Thanks in advance for your prompt response.

 

Regards

Exact!

 

Now, can you tell me why doesn't Robot find characteristic point like it has done for other beams?

Point in the middle of the beam x,rel=0.5

 

As you can see there are My moments on this beam but they are not taken into account.

 

thanks in advance

You owe this program a beer as it check number of points and displays the worst one. The ratio where you want to check it is smaller Smiley Wink
