Book Description

Excerpt from Reinforced Concrete Construction, Vol. 3: Bridges and Culverts, Prepared in the Extension Division of the University of Wisconsin This volume on reinforced concrete construction was originally planned to treat of practically all the various types of rein-forced-concrete structures not receiving consideration in Volumes I and II. The number of requests, however, for a comprehensive text on the analysis and design of arch bridges has made it desirable to devote an entire volume to bridges and culverts alone, and to leave the treatment of the remaining structures to a fourth volume to appear at some future time. The students enrolled in the correspondence-study courses in reinforced concrete in the Extension Division of The University of Wisconsin are, for the greater part, engineers in active practice throughout the country, and most of the requests above mentioned have come directly from these students who all appear to desire a text-book, treating of arch bridges, which will be neither too complex nor too much abbreviated for the average engineer to readily understand the methods set forth, and, on the other hand, will be sufficiently comprehensive to enable the reader to properly analyze and design any form of reinforced-concrete arch. The present volume is an attempt to meet the needs of the students by omitting intricate mathematical analyses involving the calculus; by avoiding mathematical sign language wherever it is found possible; and by including complete methods of design of both symmetrical and unsymmetrical arches, not only of single span, but of multiple spans with elastic piers. Two entirely different methods of arch analysis are presented in order that a check may be had on all arch computations. As in the previous volumes, an effort has been made to gain clearness by careful arrangement of the subject matter and by numerous drawings and photographs. This volume when used for correspondence-study instruction is intended to be supplemented with such material as is suited to the special needs of the individual student. If used in residence classes, the attention of the students should be frequently called to the typical designs of arch bridges in Chapter XIII. Problems to be solved by the student are not included in this text, as in the two volumes preceding. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
