Notation

E_c = modulus of elasticity of concrete, psi
E_s = modulus of elasticity of reinforcement, psi
f_c^' ₌ specified compressive strength of concrete, psi
f_y = specified yield strength for non prestressed reinforcement, psi

...

Design properties for concrete and reinforcement can be selected to following Concrete & Reinforcement Materials. In addition, design properties such as modulus of elasticity for concrete E_c, modulus of elasticity for reinforcement E_s, specified compressive strength f_c^' and specified yield strength for reinforcement f_y are available inConcrete & Reinforcement Materials title.
