Weldolet

Hey all

In my project I would like to be able to add a weldolet.
I could not find any setting which will allow me this in Rohr2.
My question is, how Rohr2 handles weldolets? Is it possible to insert a weldolet?
Thank you!

Best regards,
Ioana

I forgot to mention that the weldolet should be after EN13480.

You can use Weldolet (TWA) for EN 13480.
But you have to use alternative equations.

Ok.
I will do that.
Is this change by using EN13480 alternativ giving other changes in the calculation, or is just the alternative in order to use some different components (as weldolet) in the model?
Thank you for the help!
Best regards,
Ioana

Hi,

you can have a look in the stress-manual, there is a description of the different equation:

The main differenz in the alternative equation is, that the components of the moments (inplane/outplane/torsion) with the according sif can be considered in the calculation.

Wo muss ich in Version 32.1 das Häkchen setzen, damit Rohr2 mit Weldolets rechnet?

Hallo,

bei er aktuellen Version hat sich die Bezeichnung etwas geändert, da wir uns nun direkt auf die entsprechende Tabelle der EN13480 beziehen:

For EN13480:

in one of previous Rohr2 versions (31.2), in order to force Weldolet (TWA) to appear in component EN13480 list:

Component menu.png

we had to first click on "Use alternative equation with ii and io from table H.3"

h3.JPG

Now, I understand that from version (32.1) we don't need to first click on "Use alternative...H.3", and that TWA is already in component EN13480 menu

The question is:
In version 33.0, If we use TWA from component EN13480, and box "Use alternative...H.3" is NOT selected is it still correct for stress calculation of Weldolet?
What it means if we use TWA and NOT select "Use alternativ...H.3"?

Or do we still need to select "Use alternative..." in order to properly calculate Weldolet?

Hi

From version 33.0 we allow to mix between the SIFs from Table H1 (singel SIF) and H3 (inplane outplane SIF).
You no longer need to explicitly ask for the separate equations to be able to use the weldolets in EN13480.
In this case the higher SIF is used for the resultant moment for the elements from H3.

Best regards
