There are radical changes in the works for the concrete design standard of the American Concrete Institute. ACI committee members are about halfway through a six-year overhaul of the 502-page tome, aiming to validate its content and make it more user-friendly. It is the first major revamp in nearly 45 years.
In a big departure, the 2014 edition of the ACI 318: Structural Concrete Building Code, referenced by the International Building Code (IBC), is organized around structural members, such as columns and beams, rather than behavior, such as flexure or shear. All relevant member information, including direction to other chapters when appropriate, is in one place. Currently, requirements are scattered.
