The Strains In Framed Structures

This classic engineering text provides a comprehensive analysis of the stresses and strains that affect framed structures, and offers practical guidance for designing buildings, bridges, and other complex structures. With clear explanations and numerous examples, Du Bois makes this challenging subject accessible to students and professionals alike, and his emphasis on real-world applications makes this book an essential reference for anyone working in the field of structural engineering.

Excerpt from The Strains in Framed Structures: With Numerous Practical Applications to Cranes Bridge, Roof and Suspension Trusses Braced Arches Pivot and Drawn Spans Continuous Girders, Etc;, Also, Determination of Dimensions and Designing of Details Specifications and Contracts Complete D The present edition is essentially a new work. It appears not only in a new form, greatly reduced in size and weight, but with additions and changes so extensive and important that it is practically rewritten and reset. In the change of title from "Strains" to Stresses, we have at last conformed to the established usage of all physicists and the large and increasing majority of engineers. In changing the signs for compression, tension, and rotation we conform to the universal notation of analytical mechanics. These minor changes would have been made by the author long since had it not been for the expense, necessitating as they do an almost entire resetting of the type. The present work is thus in harmony as regards notation and nomenclature with modern practice. As to more important changes, in Part I, Section I, page 37, we have replaced the articles upon "Graphic Representation of Moments for any Number of Forces" by new and correct matter. These articles have until now appeared in successive editions, erroneous in statement and demonstration. Later writers have not called the attention of the. author to this blemish. Indeed, some have done him the favor of giving the same erroneous presentation without calling attention to its source. It is, however, hoped that in their future editions they may give him the credit of its correction. Examination of the rest of this section will reveal many other minor changes, too numerous for mention here. In Part I, Section II, many of the changes are of a more important character. On page 97 et seq. we give a revised treatment of the "Method of Calculation by Concentrated Load Systems;" also by "equivalent uniform load," by "one locomotive excess and equivalent uniform load," and by "two locomotive excesses and actual uniform train load." We also give a comparison of the results of these various methods, and point out the reasons why the last method is now and always has been preferred by the author, and used in all the illustrative examples. At the same time the matter is so presented that any method may be used, the illustrations of the application of the statical principles being so full and complete that the reader can have no difficulty in using any system of loading he may prefer.
