The phenomenal development of reinforced concrete in the last few years has brought with it new materials, new methods, new structures, and consequently, many new problems. So rapid has been the advance in the use of concrete, that the proper working out of many of these problems has lagged far behind the need of their solution. Even the materials themselves have not been thoroughly standardized. It is true that the cement, sand, and stone, and the resulting concrete have been the subjects of much study and discussion and many questions concerning them have been settled. The quality of the steel reinforcement, how ever, has, until the last year or two, been neglected.
The material used for the first reinforcing bars was the mild steel or low-carbon grade known as structural steel. This was natural as structural shapes were frequently used as rein forcement. Also, the properties of this mild steel were well known, and the mills were making it in large quantities, so that it was easy to obtain. It was early seen, however, that the maximum effective strength of the reinforcement depended upon the yield point of the material.

Paperback. Condition: New. Print on Demand. This book is a meticulous investigation into the mechanical properties of reinforcing bars, a vital component of reinforced concrete. The author examines the variation in yield point, ultimate strength, and elongation found in tension tests of reinforcing steel. The book begins by establishing the general requirements for a good reinforcing steel and their relative importance. In the second chapter, the author presents the results of his own tension tests of various sizes and types of reinforcing bars, which he then analyzes in the third chapter. Acknowledging the variability in the properties of reinforcing steel, the author concludes with a discussion of their impact on the design and safety of reinforced concrete structures. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Seller Inventory # 9780428063405_0
