Dear colleagues,

I'm interested in modelling of concrete members in detail. I'm wondering if it is possible to embed reinforcement in a concrete member (similar to Abaqus)? Is there any command?
As far as I see, there are a) fiber and b)Plane Stress Concrete models available but it is reported that the plane stress concrete model does not work properly. Could you please let me know if I'm missing anything?
Is there any way to build a nonlinear reinforced concrete section with diagonal reinforcement?

Thanks,
Pir
