Reinforced Concrete Beam Design per ACI 318-19 per ACI 318-19 §9, §18

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 nonprestressed reinforcement, psi

Design properties for concrete and reinforcement can be selected for the following https://idecad.atlassian.net/wiki/spaces/IKP/pages/1547764884. 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 inhttps://idecad.atlassian.net/wiki/spaces/IKP/pages/1547764884 title.
