This new edition of "Building Code Requirements for Structural Concrete" (Code) is the first since the reorganized format was published in 2014 and includes new and updated code provisions along with updated color illustrations for added clarity. The Code provides minimum requirements for the materials, design, and detailing of structural concrete buildings and, where applicable, nonbuilding structures. This presentation covers a few of the significant changes to this code including high-strength reinforcement, shear strength, development length, and shear lugs.

    • Understand where higher grades of reinforcement are accepted and changes to the requirements for structural concrete to allow the higher reinforcement grades.
    • Identify changes to development lengths for straight bars, hooks, and headed deformed bars.
    • Learn the new requirements for post-installed screw type anchors and shear lug design for anchoring to concrete.
    • Describe the changes to shear design provisions and equations.
