The author reviews the significant contributions of research in prestressed concrete since the beginning of this century and discusses current and future research needs. Prestressed concrete is the offspring of research. Although the principle of prestressing has been used in various ways for centuries, its successful application to concrete is relatively recent and was made possible only as a result of the understanding of the long-term deformation of concrete gained through research. Early attempts to produce prestressed concrete members failed because of insufficient understanding of the green and shrinkage characteristics of concrete and of the need to use high yield strength steel. The first major breakthrough came about when Freyssinet applied the results of his careful study of the long-term deformation of concrete and produced the first successful prestressed concrete structures. In the United States, the most significant research work was that in conjunction with building the Walnut Lane Bridge and the extensive basic research conducted at the University of Illinois. /Author/
