The significant changes that have taken place in the state-of-the-art of concrete engineering and construction during the last ten years with the extreme success and popularity in the United States and abroad of the first edition of this handbook published in 1974 has made it imperative to issue this second edition. 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.
