Prestressed concrete is widely used today in many branches of civil engineering and building construction. Elegant and spectacular structures have been created to bridge across rivers and ravines or roof over large areas - indeed the history of prestressing is rich with innovation and inspired design by brilliant engineers. Other, more mundane, applications include the manufacture of everyday structural items such as railway sleepers, piles, lintels, beams and flooring units. This publication is intended for those readers requiring an introduction to prestressed concrete, but not wishing to get involved with the complicated mathematical treatment often found in textbooks on the subject. In the following pages prestressed concrete is introduced by words and pictures in a way that should appeal to the student and the practising architect or engineer who needs a basic understanding of the concepts and technique. However, the use of some technical terms is inevitable and some design aspects are also considered.
