Mark Fintel is author of Handbook Of Concrete Engineering. He is CEO and Founder of ProAlly.
The following were.the main contributors
to the changes: many innovations in design techniques have been introduced in
the interim particularly as a result of the wide use of computers in design
offices thus allowing extreme sophistication of analysis; the ACI code that
serves as the basis for concrete design has undergone two significant
revisions-in 1977 again in 1983. This latest edition of the handbook is based
on the 1983 version of the ACI Code; progress in construction equipment and
methods; higher strength materials. The charts and tables of the chapter on the
proportioning of sections are based on the metric system making it possible for
designers in Canada and overseas to apply the metric version of the 1983 Code
to their own designs in the metric system.
