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.<o:p></o:p></p>
