Foundations of Earthquake-Resistant Structures.

  • Reqirements for foundations of earthquake-resistant structures are applied automatically according to Codes.

International Design Codes

ACI 318-19 : Foundations of Earthquake-Resistant Structures per ACI 318-19 with ideCAD

TSC 2018 :

Notation in ACI 318-19

Ag = gross area of concrete section, in2
As = area of nonprestressed longitudinal tension reinforcement, in2
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
Mcr = cracking moment, in.-lb
Mu = factored moment at section, in.-lb
