Design of Prestressed Concrete to Eurocode

Design of Prestressed Concrete to Eurocode  


For the design of prestressed concrete structures, a sound understanding of structural behaviour at all stages of loading is essential. Also essential is a thorough knowledge of the design criteria specified in the relevant design standard, including the rules and requirements and the background to them. 

The aim of this book is to present a detailed description and explanation of the behaviour of prestressed concrete members and structures both at service loads and at ultimate loads and, in doing so, provide a comprehensive guide to structural design.

 Much of the text is based on first principles and relies only on the principles of mechanics and the properties of concrete and steel, with numerous worked examples. Where the design requirements are code specific, this book refers to the provisions of Eurocode 2 (EN 1992–1–1:2004) and other relevant EN Standards, and, where possible, the notation is the same as in the Eurocode. 

A companion edition in accordance with the requirements of the Australian Standard for Concrete Structures AS 3600–2009 is also available, with the same notation as in the Australian Standard. The first edition of the book was published over 25 years ago, so a comprehensive update and revision is long overdue. 

This edition contains the most up-to-date and recent advances in the design of modern prestressed concrete structures, as well as the fundamental aspects of prestressed concrete behaviour and design that were well received in the first edition. 

The text is written for senior undergraduate and postgraduate students of civil and structural engineering and also for practising structural engineers. It retains the clear and concise explanations and the easy-to-read style of the first edition.

 Between them, the authors have almost 100 years of experience in the teaching, research and design of prestressed concrete structures, and this book reflects this wealth of experience. 

The scope of the work ranges from an introduction to the fundamentals of prestressed concrete to in-depth treatments of the more advanced topics in modern prestressed concrete structures. 

The basic concepts of prestressed concrete are introduced in Chapter 1, and the limit states design philosophies used in European practice are outlined in Chapter 2. The hardware required to pretension and post-tension concrete structures is introduced in Chapter 3, including some construction considerations. 

Material properties relevant to design are presented and discussed in Chapter 4. A comprehensive treatment of the design of prestressed concrete beams for serviceability is provided in Chapter 5. The instantaneous and time-dependent behaviour of cross-sections under service loads are discussed in considerable detail, and methods for the analysis of both uncracked and cracked cross-sections are considered. 

Techniques for determining the section size, the magnitude and eccentricity of prestress, the losses of prestress and the deflection of members are outlined. Each aspect of design is illustrated by numerical examples. Chapters 6 and 7 deal with the design of members for strength in bending, shear and torsion, and Chapter 8 covers the design of the anchorage zones in both pretensioned and post-tensioned members. 

A guide to the design of composite prestressed concrete beams is provided in Chapter 9 and includes a detailed worked example of the analysis of a composite through girder footbridge. Chapter 10 discusses design procedures for statically determinate beams. Comprehensive self-contained design examples are provided for fully-prestressed and partially prestressed, post-tensioned and pretensioned concrete members. 

The analysis and design of statically indeterminate beams and frames is covered in Chapter 11 and provides guidance on the treatment of secondary effects at all stages of loading. Chapter 12 provides a detailed discussion of the analysis and design of two-way slab systems, including aspects related to both strength and serviceability. Complete design examples are provided for panels of an edge-supported slab and a flat slab. 

The behaviour of axially loaded members is dealt with in Chapter 13. Compression members, members subjected to combined bending and compression, and prestressed concrete tension members are discussed, and design aspects are illustrated by examples. Guidelines for successful detailing of the structural elements and connections in prestressed concrete structures are outlined in Chapter 14.

 As in the first edition, the book provides a unique focus on the  treatment of serviceability aspects of design. Concrete structures are prestressed to improve behaviour at service loads and thereby increase the economical range of concrete as a construction material.

 In conventional prestressed structures, the level of prestress and the position of the tendons are usually based on considerations of serviceability. Practical methods for accounting for the non-linear and time-dependent effects of  cracking, creep, shrinkage and relaxation are presented in a clear and easy-tofollow format.

The authors hope that Design of Prestressed Concrete to Eurocode 2 will be a valuable source of information and a useful guide for students and practitioners of structural design.
