Prestressed concrete has been one of the most widely used structural materials in railway bridges, highway bridges, and civil and industrial buildings since its first trial application over 100 years ago. A prime example of its application is prestressed concrete beams, which are almost the strongest competitive superstructures in bridges with spans from 30 to 250 m. In view of the excessive deflection and cracking of some built longspan bridges that are still in service and the strict requirements for high-speed railway bridges for long-term camber or deflection, combined with the development of material science, construction technology, and structural analysis, the following trends are emerging: prestressing materials with higher strength and mechanical properties will be developed and used, the construction technologies will be more intelligent and standardized, the performance-based design will draw increased attention, and most of the analysis and design of prestressed concrete structures will be completed by computers through specific software rather than by hand. Accordingly, the textbooks or reference books for the analysis and design of prestressed concrete must keep up with new developments. This book systematically introduces the basic concepts of prestressed concrete and fundamental principles of analysis and design for prestressed concrete structures subjected to bending, shear, tension, compression, and torsion based on the ultimate limit state method.
