ACI CODE-318-25 (SI Units)

The “Building Code for Structural Concrete” (“Code”) provides minimum requirements for the materials, design, and detailing of structural concrete buildings and, where applicable, nonbuilding structures. The Code was developed using a consensus process and addresses structural systems, members, and connections, including cast-in-place, precast, shotcrete, plain, nonprestressed, and prestressed, construction. Among the subjects covered are: design and construction for strength, serviceability, and durability; load combinations, load factors, and strength reduction factors; structural analysis methods; deflection limits; mechanical and adhesive anchoring to concrete; development and splicing of reinforcement; construction document information; field inspection and testing; methods to evaluate the strength of existing structures; design verification using nonlinear response history analysis in Appendix A; performance-based wind design in Appendix B, and sustainability and resilience in Appendix C.
