Le coin des ingénieurs : Industrial Steel Structures, 2e édition

La deuxième édition révisée de Industrial Steel Structures de R.A. MacCrimmon et J. Richard a été publiée plus tôt cette année. Vous pouvez l’acheter à la Boutique de l’acier de l’ICCA (https://steelstore.cisc-icca.ca/fr). Voir la figure 1.

Cette publication de l’ICCA, qui est passée de 148 pages (dans la première édition) à 201 pages, décrit la conception d’une usine type qui soutient deux ponts roulants de 40 tonnes (figures 2 et 3). L’exemple comprend des poteaux à baïonnette avec une ferme Pratt de 24 m de portée soutenant le toit et les charges latérales. Parmi les aspects structurels couverts dans cette publication, on retrouve les normes de conception, la résilience et la température, les revêtements, les toitures à joint debout, la réhabilitation et les structures de soutien des chaudières.

La publication est fondée sur le Code national du bâtiment – Canada (CNB 2015) et la norme CSA S16-19 (Règles de calcul des charpentes en acier). Vous trouverez de plus amples renseignements dans la publication de l’ICCA intitulée Crane-Supported Steel Structures – Design Guide, 4^e édition, de R.A. MacCrimmon.

La liste des références au chapitre 10 a été doublé et entièrement mise à jour. Elle fournit des renseignements à propos des bâtiments industriels et des autres structures et sur les sujets suivants : les charges éoliennes et sismiques, les bâtiments à pont roulant, les ponts roulants et les poutres de roulement, la fatigue, la stabilité, les plaques d’assise, les assemblages en béton, les coques et les plaques générales, les réservoirs, les bennes, les silos, les canalisations, les cheminées et les réservoirs sous pression.
