Prestressing concrete technology is critical to understanding problems in existing civic structures including railway and highway bridges; to the rehabilitation of older structures; and to the design of new high-speed railway and long-span highway bridges. Analysis and Design of Prestressed Concrete delivers foundational concepts, and the latest research and design methods for the engineering of prestressed concrete, paying particular attention to crack resistance in the design of high-speed railway and long-span highway prestressed concrete bridges. The volume offers readers a comprehensive resource on prestressing technology and applications, as well as the advanced treatment of prestress losses and performance. Key aspects of this volume include analysis and design of prestressed concrete structures using a prestressing knowledge system, from initial stages to service; detailed loss calculation; time-dependent analysis on cross-sectional stresses; straightforward, simplified methods specified in codes; and in-depth calculation methods. Sixteen chapters combine standards and current research, theoretical analysis, and design methods into a practical resource on the analysis and design of prestressed concrete, as well as presenting novel calculation methods and theoretical models of practical use to engineers. Presents a new approach to calculating prestress losses due to anchorage seating Provides a unified method for calculating long-term prestress loss Details cross-sectional stress analysis of prestressed concrete beams from jacking to service Explains a new calculation method for long-term deflection of beams caused by creep and shrinkage Gives a new theoretical model for calculating long-term crack width

This book deals fundamentally with the basic philosophy, principles and the application of prestressing in structural elements. It also covers the detailed engineering of the structural elements with prestressing forces in terms of analysis and design. Different systems of prestressing, losses in prestressing and evaluation of capacity of prestressed concrete sections in flexure, shear and torsion, the force flow due to prestressing at anchorage zones, the time dependent effects due to creep and shrinkage of materials are explained. The design of prestressed concrete elements is covered with a holistic concept. In case of indeterminate structures, the effect of prestressing while satisfying the compatibility conditions has been clearly explained. The necessary philosophy and the design procedures of partially prestressed elements have been specifically dealt with. Accepted National and International Code provisions for design of prestressed concrete elements under the effect of the various loads have been elaborately discussed with worked out examples.
