Reinforced Concrete Beam Design per ACI 318-19

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.
