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, as one of the three sponsors of the Masonry Standards Joint Committee (MSJC). This committee was formed in 1978 to combine the masonry design provisions then being developed by ACI, ASCE, TMS, and industry organizations. ACI is the second of the three sponsoring societies of the Masonry Standards Joint Committee (MSJC), responsible for the development and updating of the MSJC Code and Specification (MSJC 2008a, b).
