Book excerpt: Excerpt from Continuous, Revolving Drawbridges: The Principles of Their Construction and the Calculation of the Strains in Them; With More Especial Reference to the Designing of Continuous Panel Girders of This Description This little book, in its original shape, was a paper written for the American Society of Civil Engineers, and was prompted by the author's design of the Quinnipiac Bridge, at New Haven, Conn., and by his employment in testing a design for the Eastern Avenue bridge, in Boston, Mass. It has been thought that in its present shape it may be of some use to students in engineering construction; to experts also, on the subject of continuous girders, at home and abroad, so much of the work as relates to subjects, that, it is believed, are here for the first time treated, it may not be without interest. In this connection, the author will refer only to his method of first calculating continuous girders for given reactions, and then weighing off these same reactions to act under the girders in setting them up on their supports; to those parts of the book that treat of the extension of this idea to the calculation of continuous girders, by first dividing up the total load into parts that make certain reactions = 0, and those that act on the girder as though it were continuous over all its supports; and to the cases in which two supports are themselves carried and pivoted upon a third support.
