TMS 402/602-22

Building Code Requirements and Specification for Masonry Structures contains two standards and their commentaries: Building Code Requirements for Masonry Structures designated as TMS 402-22 (and formerly designated as TMS 402/ACI 530/ASCE 5) and Specification for Masonry Structures designated as TMS 602-22 (and formerly designated as TMS 602/ACI 530.1/ASCE 6). These standards are produced by The Masonry’s Society’s Committee TMS 402/602 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.

The Code addresses the design and construction of masonry structures while the Specification is concerned with minimum construction requirements for masonry in structures. Some of the topics covered in the Code are: definitions, contract documents; quality assurance; materials; placement of embedded items; analysis and design; strength and serviceability; flexural and axial loads; shear; details and development of reinforcement; walls; columns; pilasters; beams and lintels; seismic design requirements; autoclaved aerated concrete masonry; masonry infill, veneers, glass unit masonry; and masonry partition walls. The Code Appendices address limit design and glass fiber reinforced polymer (GFRP) reinforced masonry. The Specification addresses subjects such as quality assurance requirements for materials; placing, bonding, and anchoring of masonry; and placement of grout and of reinforcement. This Specification is meant to be modified and referenced in the Project Manual. The Code is written as a legal document and the Specification as a master specification required by the Code. The commentaries present background details, committee considerations, and research data used to develop the Code and Specification. The Commentaries are not mandatory and are for information of the user only.
