Presentation Summary:
This presentation will summarize key structural design changes in TMS 402-22. A significant update involves the introduction of compression-controlled sections in strength design. As a result, some of the limitations on maximum reinforcement have been removed. Additional structural modifications include the clarification of the effective shear area, adjustments to anchor bolt steel strength, a revision of the partially grouted shear wall factor, an increase in the allowable shear friction strength, a change in the nominal shear friction strength, and several updates to the seismic design provisions. The potential impacts of these changes will be reviewed.
