Excerpt from Wrought Iron Bridges and Roofs: Lectures Delivered at the Royal Engineer Establishment, Chatham; With Examples of the Calculation of Stress in Girders and Roof Trusses by Graphic and Algebraic Methods

In the third and fourth Lectures the proportions and construction of plate web and braced girders are discussed, and in the latter the special methods of estimating the stresses applicable to braced girders. The author has always used Mr. Latham's method for parallel braced girders, the principle of which is here deduced from the simple con sideration of the shear and bending moment at a section. Mr. Latham was the first to abandon completely the formula for breaking weight and to proportion girders simply to the actual stresses due to the load, and his work is still probably the best treatise in our lan guage on wrought-iron bridges. Lastly, applications are given of graphic methods to parallel and bowstring girders.
