This session provides an overview of the major structural changes in TMS 402-22. One of the biggest changes was the introduction of compression-controlled sections in strength design. As a result of this, the maximum reinforcement provisions were deleted except for beams and intermediate and special shear walls under in-plane loads. The basis for the provisions, the impact on design, and some design aids is presented.

Other structural changes that are covered include: definition of net shear area particularly for beams, anchor bolt steel strength changing from being based on yield strength to ultimate strength, an increase of the allowable compressive force for masonry in allowable stress design, a change in the partially grouted shear wall factor, and an increase in the allowable shear friction strength as well as a change in the nominal shear friction strength for shear span ratios greater than 1. The potential impacts of these changes will also be reviewed.

Learning Objectives:

• Use the compression-controlled strength design provisions in TMS 402-22 and compare designs to TMS 402-16.
• Evaluate the change in anchor bolt steel strength in TMS 402-22
• Solve for shear friction strength for shear span ratios greater than 1 in TMS 402-22
• Name at least three other structural changes in TMS 402-22 and explain how they affect design
