Book Description
Excerpt from Engineering Construction in Iron, Steel, and Timber The modern methods of determining the safe intensity of working stresses in structures have been considered in the first chapter, and have been employed more or less throughout the work. The subjects treated in the various chapters have been considered as briefly as possible, and the numerous examples given are relied upon for more complete explanation. The special feature of the work lies in the various examples which illustrate the design of the most important classes of structures in iron, steel, and timber; these have all been selected from existing works.

Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1910 edition. Excerpt: ...continuous girders for various purposes. Two cases will be considered in the first instance: --1. When the load on any span is uniformly distributed over that span. 2. When the loads are concentrated at one or more points in a span. A third case might occur with both distributed and concentrated loads, but this could obviously be treated by combining the results of each loading considered separately. The assumptions made in the various examples considered in this chapter are: --1. That all the supports are on the same level or on the same uniform gradient. 2. That the girder is uniform in section throughout its length. With regard to the second assumption, which is never realised in bridges, in which the material is disposed in accordance with the variations in the stresses, the errors in the stresses need not lead to errors in the design of the various members of any practical importance. Let M0, M, M2 and M3, Fig. 271, denote the bending moments at the points of support A, B, C and D respectively. Let lv l2 and l3 be the lengths of the spans, and wv w.z and w3 denote the loads per lineal foot. Then, on the assumptions stated, it can be proved that--+ 2M1(Z, +12) + M21.2 + i(w2l23 + wj) = 0. This equation expresses the relation between the bending moments at any three consecutive piers; it is known as the equation of three moments, and was first demonstrated by Clapeyron. The moments M, and M2 in Fig. 271 tend to bend the girders upwards; thus in Fig. 270, which shows a continuous girder of three spans, the deflection over the piers B and C is upwards, and the diagram of upward bending moments is represented by the figure AicD, Fig. 271. The bending moments over the points A and D are zero. Beside the upward bending moments, which attain..
