Types and Details of Bridge Construction e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It is the purpose to present in Types and Details of Bridge Construction the development of advanced practice and its standard details, to illustrate the classes of structures adapted to different conditions, show some of the characteristic differences between American and foreign design and illustrate some primitive or obsolete constructions, besides recording important and well-known examples so as to have their principal data easily accessible. The first consideration in the selection and preparation of data has been in every case to show clearly the special and important features and give only what is essential to the design and present the requirements, conditions and methods involved in the construction and erection of the work. Some explanations have been added to promote clearer appreciation or interesting comparisons. Generally, when structures are essentially duplicates, only one of them is described, and the others are compared with them and their varying or distinguishing characteristics noted. The list of structures described is not complete and the classification is not absolute, but suffice to illustrate different types and show a wide range of practice in details. The bridges have been arranged in order and grouped in classes, and the descriptions are in most cases supplemented by specific references to any more extended articles which have been published about them in technical journals or professional papers, and may be consulted in libraries for additional data in special cases. Some of the most interesting data have been received especially for this book through the kindness and friendship of the engineers associated with the construction of the bridges described. In some cases these data included rare photographs and valuable drawings, and I take pleasure in expressing my thanks for them to Messrs. Theodore Cooper, F. S. Cook, John Stirling Deans, H. W. King, C. F. Loweth, Foster Milliken, C. N. Monsarrat, A. W. Munster, F. C. Osborn and J. A.
