No, of course not. Working stress design assumes linear elastic behavior of
a homogeneous (or almost) material. Ultimate strength is best for the
dissimilar material of reinforced concrete because it most closely
approximates the material behavior, in fact R.C. is why ultimate strength
design was developed. ASD is an excellent basis of assumption for steel
design and very closely matches the observed behavior of the material.
