Regarding modelling any reinforced concrete solid element (i.e. a R.C.Beam, R.C.Column, shear-wall, etc.) in the commercial Finite Element program Abaqus FEA (and/or any similar Finite-Element-Analysis-Software), WHAT are the differences, pros and cons and challenges to model or design the reinforcing-bar-elements (including longitudinal rebars, transversal rebars, stirrups, etc.) as SOLID-ELEMENTS or WIRE-ELEMENTS?
3D element is more neat to exact solution in comparison to wire or 1D element
In my opinion, the most challenge we face in 3D modeling of RC elements is modeling the interaction between concrete and steel bars.
There is also another option available in Abaqus to define rebars (Also it may be available in another FE packages). By using "Rebar layers" you can define your rebar layers based on their cross-sectional area, spacing, position, and direction. This feature can only be applied to shell sections. In my opinion its main advantage is the fast and easy modeling capability.
