Hardy Cross and the "Moment Distribution Method"Leonard K. Eaton resurrects the reputation of Hardy Cross, developer of the "moment distribution method" and one of America's most brilliant engineers. The structural calculation of a large reinforced concrete building in the nineteen fifties was a complicated affair. It is a tribute to the engineering profession, and to Hardy Cross, that there were so few failures. When architects and engineers had to figure out what was happening in a statically indeterminate frame, they inevitably turned to what was generally known as the "moment distribution" or "Hardy Cross" method. Although the Cross method has been superseded by more powerful procedures such as the Finite Element Method, the "moment distribution method" made possible the efficient and safe design of many reinforced concrete buildings during an entire generation.
À la fin du XIXe siècle, la construction de quartiers réservés aux entrepôts devient un élément important de la croissance des villes en Amérique du Nord. Ce type de quartier constitue le centre d’activité des grossistes, principaux agents de l’expansion du commerce. Souvent, les entrepôts mêmes sont remarquables du point de vue architectural. De fait, l’entrepôt reste d’ordinaire, avec la gare de chemin de fer, le véritable monument de la ville nord-américaine. Le présent article examine la façon dont s’est formé le quartier du commerce de gros.In the late nineteenth century, the construction of warehouse districts became an important part of the building process in the North American city. These warehouse districts were the centres of activity for the wholesalers who were the key agents for the expansion of mercantile capitalism. The warehouses themselves were often structures of unusual architectural distinction. With the railroad station, the warehouse was ordinarily the true civic monument of the North American city. This article studies the process by which the wholesale district was formed
