The Masonry Society (TMS): Through its technical committees, this group influences different aspects of masonry design. TMS is the lead sponsor of the Masonry Standards Joint Committee (MSJC). TMS also publishes a Masonry Designers’ Guide to accompany the MSJC design provisions.
American Society of Civil Engineers (ASCE): ASCE is a joint sponsor of many ACI technical committees dealing with concrete or masonry. ASCE is the third of the three sponsoring societies of the Masonry Standards Joint Committee (MSJC). ASCE publishes ASCE 7-05 (2005), which prescribes
American Concrete Institute (ACI): Through its many technical committees, this group publishes a variety of design recommendations dealing with different aspects of concrete design. ACI Committee 318 develops design provisions for concrete structures. ACI is also involved with masonry
American Society for Testing and Materials (ASTM): Through its many technical committees, ASTM develops consensus specifications for materials and methods of test. Although some model code organizations use their own such specifications, most refer to ASTM specifications.
Water penetration resistance of masonry depends on wall type, workmanship, and materials. In this section, additional information is presented on each of these. 1. Specification and design: a. Specify and design wall types appropriate for the severity of driving rain expected in the g
Examples of construction details for masonry structures requiring little calculation are given in the sections and figures below. These details are generic in nature. These can be supplemented by the details provided in NCMA and BIA technical notes. 1. Overall modularity: a. Overall
Design Steps for Structures Requiring Little Structural Calculation Many masonry structures require little structural calculation. Their primary design steps are layout, design involving primarily structural layout, detailing, and material specification. In this section these steps ar
Masonry accessory materials include reinforcement, connectors, sealants, flashing, coatings, and vapor barriers and moisture barriers. Each of these is described further below. Reinforcement Reinforcement consists of the following: • Steel deformed reinforcing bars meeting the require
The following characteristics of masonry assemblages are covered by ASTM Specifications E72, C1072, C1388, C1389, C1390, C1391, C1357, and C1314: 1. Compressive strength: This is often denoted by fm . Using ASTM C1314, it is measured using stack-bonded prisms whose maximum ratio of he
