Design of masonry structures
This is the fourth edition of CSA S304, Design of masonry structures , using limit states design principles. It supersedes the previous editions published in 2014, 2004, under the designation CSA S304.1, and 1994, under the designation CSA S304.1 and the title Masonry Design for Buildings (Limit States Design). Prior to the limit states design edition in 1994, there were two working stress design editions, CSA S304-M84 and the first edition of CSA S304 issued in 1977 (imperial version) and 1978 (metric version).

This Standard was prepared by the Technical Committee on Masonry Design, under the jurisdiction of the Strategic Steering Committee on Construction and Civil Infrastructure, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group
This Standard specifies requirements for the structural design of unreinforced, reinforced, and prefabricated masonry structures and components in accordance with the limit states design method of the National Building Code of Canada. This Standard also provides requirements for the structural design of prestressed masonry beams, walls, and columns in accordance with the limit states design method of the National Building Code of Canada.
Notes:
Other masonry standards Requirements for mortar and grout for unit masonry, masonry connectors, and masonry construction are specified in CSA A179, CSA A370, and CSA A371, respectively. These Standards include requirements that affect the design and are required for use with this Standard.
This Standard does not apply to the structural design of vehicular bridges.
This Standard applies to the structural design of partitions subject to loads such as wind loads, significant internal air pressure differences, seismic loads, or large eccentric loads mounted to the wall. Some unreinforced masonry partitions subject to these loads may be designed using Clause 8.17.
This Standard does not apply to the structural design of thin veneers individually secured by mortar adhesion to a structural support or to the structural design of rough stone veneer. See CSA A371 for prescriptive requirements and limitations.
This Standard does not apply to the structural design of rough (rubble) stone masonry. See CSA A371 for prescriptive requirements.
In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
