Although suspended roofs (in the general sense)
were built in the United States at least as far back as
193 1, no Standarò for the design of cable building
structures has been available previously in the
United States. In 1966, the Tentative Criteria
for Structurai AppEications of Steel Cables for
Buildings was published by the American Iron and
Steel Institute (AISI). Shortly thereafter, “design
fundamentals” were published by U.S. Steel (Scalzi
et al. 1969). The AISI Criteria was later revised to
form the Manual for Structural Application of Steel
Cablesfor Buildings published in 1973 by the AISI.
Both documents addressed the use of Zinc-Coated
Steel Structural Strand (ASTM A586), historically
known as “bridge strand,” and Zinc-Coated Steel
Structural Wire Rope (ASTM A603), which is
commonly termed “bridge rope.” In the current
Standard, the use of a wider range of metal wire
strand and wire rope products is addressed.
Furthermore, in contrast to the Criteria and the
Manual, the Standard is in mandatory language
