that's what I figured, I was trying to use "wall element" because it can automatic design the reinforcing, "Plate" can only do the analysis, you have to read the result and then do the design yourself. I will try both to see the difference.
I am modeling a circular concrete bin in Risa 3D with several connected walls with sheared node(joint), are they gonna transfer loads between each other? if not should I just use plate?
