Concrete slab

szicsa

Dear All,
I'm not quite experienced with Mecway. So i would like to ask some advice to model an rc slab supported by columns. My question is rather general at that moment. I know how i can create shell elements but i'm confused about rebars. How the rebars can be considered inside the modelled shell element. Maybe some combined material properties? I don't know. i assume to build a complete detailed model with all the rebars plus the concrete around them would cause infinite simulation. If any of you had a previous simple input file that could be a great help to understand it
Thank you for your help,

Csaba

There's no special material for reinforced concrete. You might be able to simulate it using a laminate. I don't know how you'd convert rebar to an equivalent stack of orthotropic materials though, or even if it's possible in general.

Thanks Victor,
It seems that it makes sense. In the meantime, I have read a few article in this topic. The most typical approach, in general FEA, to use a shell element for the slab with rebar layers. I assume that would be the same that you mentioned with laminates in Mecway.
