ABSTRACT
This paper reviews changes that are being made to the 2016 Edition of Building Code Requirements and Specification for Masonry Structures (TMS 402/TMS 602). Some of the major
technical changes include the addition of shear friction provisions, changes to anchor bolt capacity in shear crushing, and deletion of prescriptive requirements for piers in strength design. Nontechnical changes include simplification of quality assurance requirements, consolidating lap splice and development length requirements, and clarification of provisions. In addition, several definitions were added and consistent terminology was adopted in several cases. Because of the extent of these changes, the paper will provide background on what changes were made, and also reasons why the revisions were needed, thus allowing the paper to serve as a means to update users on these important changes and also making the paper a future historical reference on the revisions. In addition, the Committee that maintains these provisions will be moving to a 6-year revision cycle (2016-2022) for the next edition of the standard. Reasons for this change, benefits and potential drawbacks from the longer cycle, and considerations for future revision cycles are also reviewed.
