    CABLE-STAYED BRIDGES OF PRESTRESSED CONCRETE Walter Podolny, Jr. Bridge Division Federal Highway Administration U.S. Department of Transportation Washington, D.C. Discusses prestressed concrete cable-stayed bridge structures. Although most cable-stayed bridges have been of steel construction, a few have been made of prestressed concrete. This type of structure is presented on a case-study basis with the intent of encouraging designers to consider the feasibility of using this type of structure which in some instances might be a more appropriate choice.

  • Chapter 2: Literature Review
    CHAPTER 2: LITERATURE REVIEW The following chapter shall introduce the reader to past, present, and future in bridge engineering. The history of engineering is as old as mankind itself, and it is without doubt that technical progress and the rise of human society are deeply interwoven. Bridges have often played an essential role in technical advancement within Civil Engineering. The development of important types of bridges and the changing use of materials and techniques of construction throughout history will be dealt with in the first part of this chapter. Notably, manifold legends and anecdotes are connected with the bridges of former eras. Studying the history of a bridge from its construction throughout its life will always also reveal a fascinating picture of the particular historical and cultural background. The second part of this chapter introduces the main challenges that the current generation of bridge engineers and following generations will face. Three important areas of interest are identified. These are improvements in design, construction, maintenance, and rehabilitation of a bridge, application of high-performance materials, and creative structural concepts. As technology advances, many new ways of innovation thus open for the bridge engineer. 2.1 HISTORY OF BRIDGE CONSTRUCTION The bridges described in the following sections are examples of their kind. A vast amount of literally thousands of bridges built requires choosing a few exemplary ones to show the main developments in bridge construction throughout the centuries. Any book examining bridges in a historical context will make its own choice, and studying these works can be of great value for understanding of the legacy of bridge engineering.
