hi,
i got this design result for one of the beams in my model.
i find it weird since the Vy,Ed value is very small.
can anybody provide the extended calculation for Tau,ty,Ed, and how it comes to that value 1.45 ?

Please check the torsion (stress due to torsional moment) in this bar rather than shear.

You were right. It was from the torsional moment. I checked it and i got the 1.45 value.
Thanks.
One more question.
In my attempts to find a solution, I opened the detailed design window.
I set some stiffners, thicked all the verification boxes (web stability at shear, at compression, etc.)
Then I hit the Calculation button and got the results. After that I did some modifications to the stiffners ( increased the thickness ). When i tried the do the calculation again, the mouse cursor changet to "working" but when in changed back to normal i didn't get the results anymore.
Any ideas why?
I would need the step by step description of your actions or a movie (plus the model) to run some test and try to investigate the situation you described.
I attached a picture with the steps I did (numbered from 1 to 8).
I tried to attach the model too, but it seems the zip file it's too large 😞
Is your file saved with or without results? Try to save it under a new name selecting rtd without result and then compress it. In addition copy the spacing of ribs from the field and paste it on the forum so that I can see it in full. Thank you.
I couldn't make it smaller. Probably there were results stil in the file and i didn't know how to discard them.
I selected all the structure and used the "Save substructure" button. Hope that's fine.
I set the stiffener distances as it followes: 0.00 ; 3.00 ; 6.00 ; 9.00 ; 12.00
(meter) absolute distances.
the beam is 12 m long
I have followed the steps you described but in my case the results are correctly displayed after making changes to the location of the stiffeners and their thickness. Try to close Robot and then load the file again and check if you are able to run the detailed analysis.

That's what i did.
And it worked agan one time, then no more.
I maybe should try reinstalling.
Could you make a movie that show exactly all your actions please? I'll try to follow. Perhaps there is something that we do in a different way and the movie will help me to find the reason.
I could record a movie. You mean using a desktop recording tool, right? Could you recomend me one?
Or is there another way?
Hello, sorry for the delay.
I captured a footage of how i modify the values. This time it took a little bit more to make it not work, but other times i took only one modification.
There are two parts of the footage. The first one you may want to skip since it contains the calculation of the model.
I'm sorry but the movies seem to be corrupted. Could you check them please?
hello,
i managed to record a footage.
here it is.
apparently it happens when I unthick some calculations and then thick them again ant then try to run the calculation
here is the file http://dl.transfer.ro/transfer_ro-07mar-d0f10145eb1f3d.zip
As you probably expected nothing like this happens on my PC however I noticed one strange situation on your movie that I would like to confirm. After opening the detailed analysis window you have all check boxes for verification marked. Then you switched off 3 bottom one and the note was opened. Then you closed the note and in the detailed analysis window only the last check box remained unchecked. Were the other two automatically marked on when you closed the note or you made his change but this part is not shown on the movie?
No, I thicked the two boxes after i closed the calculation window. They were not automaticly thicked. It's not shown due to low fps i guess. I remember that I clicked very quickly and the said to myself afterwards that I should do it slower.
As you saw, neither in may case, it doesn't do this "not showing window" all the time. And I noticed that it never happens the first time i run the calculations. Maybe it's because of lack of resources (old PC), i don't know.
Anyway it's not very bothering, so if you consider it an isolated case I think we can close the post 🙂
If you have any other ideas regarding the subject, or if you would like another movie, I'll be glad to help.
lack of resources (old PC),
Is it 32bit OS? If 64 what is RAM size?
