February 8, 2008—The American Concrete Institute (ACI) revealed its updated building code, ACI-318-08, during the World of Concrete tradeshow on January 23 in Las Vegas.
The changes mark the first major revisions since 2005 related to structural concrete construction, design, and commentary. The 467-page publication is expected to be adopted in the 2009 International Building Code. It additionally satisfies the requirements of ISO 19338:2007, “Performance and Assessment Requirements for Design Standards on Structural Concrete.”
Building Code Requirements for Structural Concrete covers the materials, design, and construction of structural concrete used in buildings and where applicable in nonbuilding structures. The Code also covers the strength evaluation of existing concrete structures.
Among the subjects covered are: drawings and specifications; inspection; materials; durability requirements; concrete quality, mixing, and placing; formwork; embedded pipes; construction joints; reinforcement details; analysis and design; strength and serviceability; flexural and axial loads; shear and torsion; development and splices of reinforcement; slab systems; walls; footings; precast concrete; composite flexural members; prestressed concrete; shells and folded plate members; strength evaluation of existing structures; provisions for seismic design; structural plain concrete; strut-and-tie modeling in Appendix A; alternative design provisions in Appendix B; alternative load and strength-reduction factors in Appendix C; and anchoring to concrete in Appendix D.
