Book Description
Excerpt from A Treatise on Wooden Trestle Bridges, and Their Concrete Substitutes: According to the Present Practice on American Railroads IN revising this work it is believed that it has been brought down to the present time. While at first glance it might seem as though the wooden trestle bridge was losing its importance in railroad work, it and its substitutes have in reality been growing in impor tance. Wooden trestles may be gradually disappearing from main lines of heavy traffic, but the increased growth of branch lines or feeders and of trestles at manufacturing plants and for electric railways have probably more than kept pace with its abandonment on main lines.

Book Description
Excerpt from A Treatise on Wooden Trestle Bridges: According to the Present Practice on American Railroads The favor with which this work was received encouraged the author to make a thorough revision upon the exhaustion of the first edition. Much new matter has been added and an endeavor made to embrace any new ideas, improvements, or knowledge derived since its first appearance, in fact to make it exhaustive as to the present knowledge and practice of trestle building. Among the more important additions of new matter are the following: To Chap. II much has been added as to the life of piles on different roads; many examples quoted of particular cases of the bearing power of piles; effects of shoeing and overdriving piles; formulas for the bearing power of piles and rules to be observed in pile driving; and additional records of cost and rate of pile-driving. To Chap. III have been added plans and a description of a water-jet pile-driver and data relating to the use of this method. To Chap. V been added a section on rail-spiking, giving a method of preventing the creeping of rails on bridges. To Chap. VI much has been added on the subject of trestles on curves and methods of elevating the outer rail. Chap. XII, treating of some of the timbers suitable for bridge building, is entirely new. Chap. XII, on the Theoretical Considerations of Design, is also new and was kindly contributed by Mr. W. W. Crehore, Assoc. M. Am. Soc. C. E. In this chapter will be found some very useful tables on dimensions of stringers and safe loads on posts, as well as a table giving the sizes of steel I beams equivalent under the same conditions to different sizes of wooden stringers. In Part II, under the head of Standard Trestle Plans, Plates XXXIX to XLV are new. Attention is particularly called to the Two Medicine Bridge and the Mountain Creek Bridge, two very high structures. In the descriptive matter of the latter the details of cost are given. Plate XLV gives the plans of a light trestle built on a very sharp curve and a very steep hillside.

Book Description
Excerpt from Detailed Design of a Railroad Bridge The stresses in the structure are caused by its own or dead weight and by the live or moving load. The dead load may be divided into two parts, the weight of the floor system consisting of rails, ties, track fastenings, stringers and floor beams, and the trusses and bracing. Excerpts from Cooper's specifications relating to these loadings are the following. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Proceedings of the Twenty-Fourth Annual Convention of the American Railway Bridge and Building Association: Held at Los Angeles, Cal., October 20-22, 1914 I think if you will take the advice of Mr. Platt, and stay over a few days, following your deliberations, you will decide you want to comevback. Other people who came out got the bug and came back. I want you folks to do the same. I do not know of any class of people in the world who could so act in harmony with us, work in harmony with us, and work to the standard of southern California as could the bridge and building people. I wish you gentlemen knew about building bridges what I do not know. I can say to you, however, that 11 had considerable experience last year in spanning that which was caused by the storm. We did not stop to build bridges. We did the next thing, we built as Robinson Crusoe did, and used the available material. I might tell another little story by way of illustrating what you people have to do, and what we did up in Wisconsin. There was a man who had worked for some time in Antigo. Being thrifty he thought he would go into business for himself, but he did not have the equipment necessary to carry on the work as he had in the old institution. 1on one occasion it was necessary for him to use some glue. He sent Mike to the basement for it. Mike was gone some time. When Mike returned the man said, Mike, never mind, I used some clay. SO it is with you bridgemen. You are the class that has to overcome obstacles; you must avail yourselves of the elements. You are of the class that can not use any shoddy on your work, because after you give it to us to operate, it is put to that physical test that determines the value Of your work. For that reason, you of all men working for a rail road company, can least afford to do that which is shoddy.
