The American Concrete Institute (ACI) announced the release of ACI 318-08, "Building Code Requirements for Structural Concrete and Commentary" and offers a summary of the incorporated changes.

ACI 318 is a must-have standard for all concrete design, construction, inspection, repair, and research professionals. It contains the latest code requirements for concrete building design and construction alongside the corresponding commentary, and includes several improvements and changes from the 2005 edition.

"Everyone from engineers, architects, contractors, specifiers, and building officials, to students and professors, regularly use ACI 318," said William R. Tolley, executive vice president of the American Concrete Institute. "Members of ACI Committee 318 have volunteered thousands of hours to ensure that necessary updates have been made to this 2008 edition, dedicated to enhancing the safety of concrete structures."

ACI 318 is a leading concrete design reference for building codes worldwide. It is expected that the updated code will be adopted in the 2009 International Building Code (IBC). ACI 318-08 is also deemed to satisfy the requirements of ISO 19338:2007, "Performance and Assessment Requirements for Design Standards on Structural Concrete."

This fall, ACI and the Portland Cement Association (PCA) will offer in-depth seminars to highlight and explain the changes in the 2008 code. Details of the seminars, including dates and locations, will be available this spring at
