Courtesy Carlos Fernandez Casado s. Although historically prestressed concrete has experienced a slower start than reinforced concrete and its development has followed a different path, it has evolved into a reliable technology and has established itself as a major structural material.
Prestressed concrete has made significant contributions to the precast manufacturing industry, the cement industry, and the construction industry as a whole. This has led to an enormous array of structural applications from bridges to nuclear power vessels, from buildings serving every use and occupancy to ships, and from lowly products, such as ties and piles, to monumental TV towers, and offshore drilling platforms.
Seldom is a major construction project planned today without prestressed concrete being considered as one of the viable alternative solutions. A careful analysis of future trends indicates a substantial increase in the use of prestressed concrete. This is also supported by developments in partially prestressed concrete, which integrates both reinforced and prestressed concrete and treats them as the extreme boundaries of the same system.
It has become almost inevitable to consider each material separately without considering their combination. The term structural concrete is increasingly used to allow both.
A similar trend is expected at the educational level. Design courses in prestressed concrete will be more widely offered at universities and may be moved from the list of technical electives to the list of required courses in structural engineering curricula. It is also likely that reinforced and prestressed concrete will be offered as part of the same general course or course sequence on structural concrete, hence essentially covering partially prestressed or partially reinforced concrete.
Audience and Educational Strategy. This book is written for advanced students and professionals. It is meant as a thorough teaching text, as well as a reference tool. It emphasizes the fundamental concepts of analysis and design of prestressed concrete structures and provides students a sufficiently strong basis for handling everyday design problems, and the tackling of the more complex problems with confidence.
A particular effort is made throughout to synthesize and condense the essential information and to give an overview of the directions in which the design is proceeding. Self-sufficient logical design flow charts summarizing the step-by-step design procedure and containing all necessary design equations are often presented. They reduce the burden of guesswork and iterative tryout encountered in the design process, and are essential when programmable calculators and computers are used.
Important formulas and equations are also condensed in tables for ready use. To provide a correlation with reinforced concrete design and to help engineers already familiar with reinforced concrete, the case of partially prestressed or partially reinforced concrete is often addressed. An extensive selection of references is given at the end of each chapter. An attempt was made to include not only necessary readings but also most recent research conducted in the United States for up-to-date information.
When appropriate guidance is not available in the code, suggestions are made to accommodate at best the intent of the code. Whenever possible, widely accepted symbols, such as those used in the ACI code are adopted and all symbols used in the text are defined and summarized for easy reference in Appendix A. A consistent notation and sign convention is followed throughout, allowing rigorous treatments when needed.
This is essential, for instance, in the case of continuous beams where the sign of secondary moments cannot be visualized a priori and must be derived from the analysis. Because of the inevitable future conversion from U. However, because the prestressed concrete industry is not on the verge of change from U. In addition, SI conversion factors and Sl equivalents for some dimensionally inconsistent equations used in various flow charts are given in Appendix B.
Compared to the first edition released in , this second edition is comprehensively expanded; it incorporates a countless number of minute improvements generated during more than twenty years of teaching and research since the printing of the first edition.
These have added broader knowledge and technical wisdom to the material. Overall, more examples are given, numerous clarifications are provided, the number of figures and photographs is augmented, and, when relevant, remarks summarizing the author's opinion that may differ from codes are added.
A chapter on strut-and-tie modeling has been added. The two main U. Functional Organization. They provide a general background on materials properties, design philosophy, and codes. They include analysis and design for flexure by the working stress design method with an introduction to optimum design Chapter 4 , analysis and design for flexure by the ultimate strength design method with full coverage of partial prestressing Chapter 5 , design for shear and torsion and their combined effects with flexure Chapter 6 , design for deflection control with treatment of partically prestressed cracked sections and the incremental time-step method to predict long-term deflection Chapter 7 , and prediction of prestress losses either by lump sum estimates or by the accurate incremental time-step procedure Chapter 8.
They cover composite beams Chapter 9 , continuous beams Chapter 10 , one- and two-way slab systems Chapter 11 , prismatic tensile members and cylindrical tanks Chapter 12 , short and slender columns Chapter 13 , and bridges Chapter Several appendixes are given at the end of the book, including a list of symbols Appendix A , SI conversion factors Appendix B , technical information on some post-tensioning systems Appendix C , and answers to selected problems Appendix D. The general organization of this book remains essentially the same as in the first edition.
Chapter 15, on strut-and-tie modeling, could be presented following Chapter 6 on shear and torsion. The material in the book is extensive and can cover up to two courses in prestressed concrete spanning from the senior undergraduate level to the advanced graduate level.
Tentative course outlines are suggested next. Course 1, Part 1: Fundamentals of Prestressed Concrete. Students can read the remaining material on their own as reading assignment and will refer back to these chapters when other topics are covered such as deflection, losses, columns, etc.
Besides explaining the general philosophy of design as applied to prestressed concrete, explain curvature, the C-line or C force concept, load-balancing concept, and how prestress losses are bypassed in preliminary design by using the factor '7. Depending on the time available, parts of certain chapters may be omitted. For instance, skip the design of anchorage zone in Chapter 4. In Chapter 6, omit the section on combined shear and torsion.
In Chapter 7, the long-term deflection by incremental time steps could be left out to a more advanced treatment. Devote eighteen to twenty lecture hours for Chapters 4 to 7. Students involved in research may benefit greatly from the treatment of losses by the time-step method, because it involves a deeper understanding of material behavior and its implication on structural response.
However, generally, most students are less interested in probing prestress losses further than the minimum needed. For this reason it is suggested to leave the treatment of prestress losses to this later stage in the course. Also, it is recommended to leave the treatment of losses due to friction and anchorage set to a second course.
Devote about two hours to this chapter. Course 1, Part 2: Applications. In a second part of a first course, analysis and design related to specific applications are covered. The selection of topics should depend on the interest of the audience and the time available. Six lecture hours may be needed. As an alternative, an introduction to secondary moments and Chapter 10 could be presented. Based on years of teaching, it has been the author's experience that Parts 1 and 2 described above would amply cover a semester-long course on prestressed concrete, assuming time is allocated for two mid-term and a final exam.
Course 2: Advanced Topics in Pretressed Concrete. Parts of chapters that were omitted during the first course, such as anchorage zone design, prestress losses due to friction and anchorage set, and combined design for shear and torsion, could be covered during this second course as well. Also, it is strongly recommended to assign a term project with some research orientation as a necessary requirement for this second course.
In writing this text, I have attempted to synthesize and convey what I have learned and practically experienced in working with prestressed concrete to date. I believe that a current level of knowledge is only fully understood when a higher level has been attained and exploited. It is my sincere hope that those who will seek knowledge in this book will not be disappointed and will use it to further expand the knowledge base of prestressed concrete for the next generation.
The acknowledgments 10 the first ed iti on remain applicable and are reproduced below. Although the author is the main dri ving force in a textbook writing project, an infinite number of minute tasks contribute to its creati on.
I am indebted to the many students who look my courses on prestressed concrete at the University of Michigan over the past tWCnlY years, and who have influenced the approach followed in this second edition by asking pertinent questions and pointing out needed clarification or improvements to the first edition.
For the past four years, since I have decided to work on this second edition, many students some by now colleagues and friends have helped me review the material in various c hapters, check the numerical accuracy of the examples.

Since about 30 years, my main research efforts have focused on the following particular fields of civil engineering: prestressed and partially prestressed concrete, high performance fiber discontinuous reinforced cement based composites, ferrocement continuous reinforcements and thin laminated cementitious composites, hybrid composites, integration-tailoring of advanced materials in structural applications, material optimization for structural performance, and structural design. In less traditional areas, I have been also working in the special field of external prestressing and fiber reinforced polymeric FRP reinforcements and their applications to new construction as well as to repair-rehabilitation-strengthening of existing structures. More recently, I have looked into developing special fibers for use in concrete with the particular characteristic of providing a slip-hardening bond behavior under pull-out for high energy absorption applications; such fibers are key to the practical implementation of high performance fiber reinforced cement composites in structural applications. My research often includes the integration of advanced materials in special structural applications or concepts.
