Beam Provided Reinforcement - Capacity for bending in ULS is not sufficient

Anonymous — Fri, 08 Jun 2018 18:52:57 GMT

I'm receiving the message "Capacity design. Capacity for bending in ULS is not sufficient for span No. 1" in provided reinforcement calculations for Eurocode

"Axial force take in account" is already checked.

Someone could give a hint what is about? What Eurocode item is the problem and what is the meaning of Axial force take in account?

Hi @Anonymous,

You actually design the beam for the combined action of axial force and bending moment (rather than the bending moment alone) and the generated reinforcement / beam size is too small.

Thanks Artur,

Robot does not have support for Brazilian codes, then I'm struggling to adapt Eurocode for this purpose.

Did you know here in Eurocode the "Capacity for bending in ULS is not sufficient" is related? This message seems to be a complete nonsense as a 4.5m long beam of 15x45cm, 25MPa concrete, failing to support 20kN.m.

Found It, the problem is not the beam/reinforcement, is the anchorage at column... In fact, adding more space on column solved the issue.

Thanks for the attention.
