ideCAD Structural automatically designs reinforced concrete beams per ACI 318-19.
Ec = modulus of elasticity of concrete, psi
Es = modulus of elasticity of reinforcement, psi
fc' = specified compressive strength of concrete, psi
fy = 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 Ec, modulus of elasticity for reinforcement Es, specified compressive strength fc' and specified yield strength for reinforcement fy are available inConcrete Reinforcement Materials title.
