ideCAD automatically designs Foundations in accordance with ACI 318 Chapter 13.
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 nonprestressed reinforcement, psi
Design properties for concrete and reinforcement can be selected to be in accordance with 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.
Requirements and reinforcement of earthquke resistance structure foundations described in this title are done automatically according to ACI Chapter 18.
Examples of foundation types covered by this title are illustrated in ACI Fig. R13.1.1.
