ACI TMS 402/602:2022

TMS 402/602 Building Code Requirements and Specification for Masonry Structures contains two standards and their commentaries: Building Code Requirements for Masonry Structures (TMS 402) and Specification for Masonry Structures (TMS 602). The Standards are written as legal documents so that they may be adopted by reference in building codes. The Code (TMS 402) covers the design and construction of masonry structures while the Specification (TMS 602) is concerned with minimum construction requirements for masonry in structures. The commentaries present background details, Committee considerations, and research data used to develop the standards. The commentaries are not mandatory and are for information of the user only.

These standards are produced by The Masonry’s Society’s TMS 402/602 Committee and were formerly developed through the joint sponsorship of The Masonry Society (TMS), the American Concrete Institute (ACI), and the Structural Engineering Institute of the American Society of Civil Engineers (SEI/ASCE) through the Masonry Standards Joint Committee (MSJC). In late 2013, ACI and ASCE relinquished their rights to these standards to TMS who has served as the lead sponsor of the Standards for a number of years. Since then, the Committee has operated solely under the sponsorship of The Masonry Society, and the Committee’s name, and the names of the standards, were re-designated.
