Excerpt from Reinforced Concrete: A Manual of Practice This book is intended to be what its title indicates, A Manual of Practice. The intention in the sections on design has been to keep within the usual requirements of the ordinary conservative building ordinances of American cities. This explains the use of the straight line formulas for stress and the limitations imposed by the employment of working stresses. The ambitious designer wishing to learn more of the theory of the subject and the design of higher structures can go to the larger standard treatises and have nothing to unlearn. So far as construction is concerned, the principles stated herein as the result of personal experience, apply to all manner of work in reinforced concrete, and to this extent the -book should be of some value to a large number of men. Good work manship implies no knowledge of, or dependence upon, theory of design. It simply calls for the exercise of common sense, unremitting vigilance and care on the part of the man in charge, a willingness to learn from every intelligent workman on the job, and the kind of pride that takes honestly to heart the les sons of experience. The motto, if the manager is the sort of man who believes in mottoes, is Do not forget! If the manager, however, does not know something about the theory of design, then the owner is taking great chances. The man in charge should be an engineer. The writer feels the preface would be incomplete unless he acknowledged here the assistance given him by his son George Seymour Mccullough in checking and recalculating the tables, many of them original. The work was at times irksome, and we trust no errors will be discovered. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
