TMS 402/602-22 Night School – Session #3

This session of the TMS 402/602-22 Night School will review the changes to the provisions in Chapter 7 and Appendix C that effect the seismic design of masonry structures. This will include revisions to the requirements for special reinforced masonry shear walls, changes to the requirements based on the assigned Seismic Design Category, and changes made to the treatment of seismic displacements in the masonry code, including a new deformation compatibility provision. The potential impacts of these changes will also be reviewed.

Learning Objectives:

• Review the changes made in TMS 402/602-22 that affect seismic design
• Understand the technical background for the revisions to the provisions for special reinforced masonry shear walls.
• Review the relationship between ASCE 7-22 seismic displacements and the TMS 402 provisions including the use of MCER displacements.
• Understand the new deformation compatibility provision and its application.
