because reinforced concrete is not homogeneous, the materials is high nonlinearity, cracked section so an elastic FE is not applicable. it's mean you ca not use result directly, integrate stress to equivalent force and place concentrate reinforcement far from section cg.
just compare with elastic FE analysis for normal beams and normal column, infinite stress at corner is the same problem.
