Currently, revisions to the 2016 edition of Building Code Requirements and Specification for Masonry Structures (identified as TMS 402 and TMS 602 respectfully) [1] are being considered
for the planned 2022 edition. This paper reviews the major expected revisions to these Standards which will include a complete revision to the veneer provisions, the addition of tension-controlled
and compression-controlled sections for strength design, the likely elimination of the empirical design method, the movement of the infill provisions from an appendix to a Chapter and more. Reasons for these and other changes are given, as well as possible needs for future enhancements of the provisions.

In addition, for this Code revision cycle, a 6-year period was intentionally, and perhaps singularly, used over a more typical 3-year revision cycle. Reasons for this longer period are reviewed, but more importantly the authors’ and committee’s observations on the longer revision period are given related to effectiveness. Recommendations for future revision cycles with advantages and disadvantages are then provided so that future leaders can consider the benefits and drawbacks of longer revision cycles.
