Hi to all,

I have run the same model under EN13480 in versions 5.0 and 5.30.
The surprise arises when I compare the bending and torsion stresses in both models for TEE branch elements where SIF is applied (i.e. unreinforced).

Although the SIF calc. give us the same values and all the obtained global element forces and moments are equal, the showed bending stresses are very different. More than twice higher in v. 5.0 than V5.30(with the corresponding overstresses).

This only happens when SIF type from the menu is selected (unreinforced, welding...)
We only obtained the same stress value selecting the SIF cell blank and introducing manually the hand calculated io and ii SIFs.
Even introducing manually the values, if for example unreinforced is selected, the stress values are different.
We think that any kind of reducing factor is included, based on the type of SIF, but we did not found any reference for that in the 2012 ed. for EN13480.

Any clarification on this issue would be highly appreciated,
Best regards,
Jhero

Jhero,

go to the configuration window ,in SIFs and stresses section,there is an option which you could choose to either use the single SIF value or to use in-plane/out-plane SIF's. make sure that the set ups for both calculations are the same.

cheers,

Hi pooria1978,

thank you for the answer,

yes, we tried also with this option and the results are the same. If you choose any of the predefined SIFs from the menu (unreinforced, welding...), Caesar V.53 includes a reducing factor to obtain the bending stresses.

We only obtain the same values of V5.0 if the SIF cell is selected blank and SIF in/out plane are introduced manually.

Regards,

Jhero

This shouldn't be happening. Open a Support Request in eCustomer and send in both the v.5.00 job and the v.5.30 job.

Hi jhero,

Is this also happening in version 5.2? I don't have 5.3 right now so I couldn't check.
