The American Concrete Institute has released ACI 318-19 Building Code Requirements for Structural Concrete.
The document includes:
— Major technical changes in higher reinforcing steel yield strengths
— The addition of shotcrete and deep foundation provisions
— Seismic requirements for deep foundations and other applications
— Vertical seismic motions
— Nonlinear analysis for seismic design
— Modification to development length equations
— Updated shear design provisions and equations
The document also identifies qualification training programs for inspectors/installers and lists certification requirements. The final code requirements of ACI 318-19 are expected to be referenced in the 2021 International Building Code.
