Hughes-Liu in Abaqus

[alima2065]

Hi everybody,
I need to model the nonlinear behavior of a large reinforced concrete structure but not with detailed solid elements. Is there any possibility in Abaqus to use beam element (like Hughes-Liu in Ls-Dyna) and define rebars inside?
Thanks

Sure, Abaqus has a feature called stringer reinforcement meant specifically for such purposes. Check it in the documentation. It’s also possible to place beam elements inside a solid part and apply the embedded region constraint to make them transmit loads together.

Thanks for your reply. But I think it is not sth that I need. I need a wire beam element that I can define section with reinforcement. So I don't want to use any solid or shell elements. Both stringer reinforcement and embedded region are applicable to solids or 2d surfaces.
Best regards,

So you want to use only beam elements and define reinforcement for them ? It’s possible with the *Rebar keyword:

*Rebar, element=beam, material=…, name=…

Check the documentation chapter "Defining reinforcement" (paragraph "Defining rebar in Abaqus/Standard beam elements").
