The reduction in cost through reduced weight is enlarged by the use of fewer joints reduced field riveting simplification of the joints by the uni formity of the sections. Reduction 0 the. Number of different ieces to handle, thereby simplifying and reducing the cost of shop work an erection.
Economic bridge design is so far removed from an exact science that the ideas of what should be the weight of long sim li(' spans varies between difl'crent engineers from 50 to 100 percent. As in icated by the discussion Trans. Am. Soc. C. E. 1922, page 9135, where Mr Steinman states his. Careful estimate of a sim lo 775-foot span based on detail calculations of all sections under the A. It. A. Specifications shows a weight per lineal foot. Of pounds, while the writer estimates the weight of two similar spans at half that amount. Mr. Lindenthal in the same. Paper believes a two-span con tinuous truss saves 20 percent over two simple spans, whereas the author figures that the continuous truss spans are 40 percent heavier than two simple spans should be.
This divergence in weight is not to he. Wondered at when we consider the A. R. E. A. Specification in its broader aspects, to wit: The. Depth of trusses shall not be less than one-tenth of the span, Art. 51. Art. 12, panel lengths shall not exceed l'/2 times the width center to center of trusses. Now the economic proportions for even the 200~feet through span are 2542 times as great as the limitations of this specification.

Paperback. Zustand: New. Print on Demand. This book delves into the realm of railway bridge engineering, exploring their structural design principles with a focus on economic optimization and rigidity enhancement. The author, an experienced bridge engineer, comprehensively examines the evolution of bridge designs, analyzing the historical progression of locomotive weights and their impact on bridge load capacities. The book delves into the intricacies of bridge design, discussing the conventional uniform load method and advocating for a rational equivalent uniform load approach to simplify computations while maintaining accuracy. It emphasizes the importance of considering impact forces, providing a consistent formula to account for both vertical and lateral effects, thus ensuring structural integrity under dynamic loads. The author presents a detailed investigation into the economic proportions of beams and plate girders, exploring the relationship between web thickness and flange area, and establishing guidelines for determining the optimal depth of girders based on stiffness and weight considerations. The book also examines the benefits of continuity in stringer design, demonstrating the advantages of reduced weight and enhanced rigidity when multiple spans are interconnected. Through rigorous mathematical analysis and practical examples, the book provides a comprehensive understanding of the factors influencing bridge design, enabling engineers to optimize structural performance while achieving cost-effective solutions. Its insights are essential for advancing the field of bridge engineering and ensuring the safety and efficiency of railway infrastructure. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
