RC beam design problem

Good morning everybody,

 

I'm having problem with the design of the rc beam 130 in my model. I have to design one rc beam and one rc column, for all the user defined load combinations (a lot, due to italian regulation), but when I run the calculation I have always this message:

 

Beam 130 ISSUE.jpeg

 

Probably there's something that I'm doing wrongly, I'm not an rc expert user, my daily job is 99.5% made of steel.

 

Thank you in advance for your help.

 

Greetings

Hi @StefanoPasquini6790

 

I run RC claculation under BAEL91, and i got a first waring before your's, saying that shear from truss (IPE) can't be taken into account.

Hi @Simau,

 

this message was related to the simplified combination rules. In my model I have some elements (bracings) in only tension/compression behaviour that can't be taken into account to define the simplfied combination. When you erase the auto combination generation, and leave only the manual combination, this message disappear and the problem of rc design remain.

 

Thank you for your time.

Hi @StefanoPasquini6790

 

The issue is due to the flatness of bar (130) and the indicated panel in the attached capture. If you try to correct the flatness of the panel and redefine this bar gain .then every thing will be like charm.

The corrected file is attached
