Betonplatten sind das haufigste Tragelement im Hochbau. Seit der EinfOhrung der partiellen Vorspannung wird bei grosseren Spannweiten die Stahlarmie rung oft durch eine Vorspannarmierung erganzt oder ersetzt. In letzter Zeit wird auch die Vorspannung ohne Verbund mit Litzen in PlastikhOllrohren an gewendet. Das letztere System bringt aber nun Probleme in der Berechnung. indem rela tive Verschiebungen zwischen Litze und Beton stattfinden konnen. Somit trifft die Obliche Hypothese vom Ebenbleiben der Querschnitte nicht mehr zu. In der vorliegenden. als Doktorarbeit verfassten. Studie untersucht Herr P. Ritz dieses Problem und leitet verschiedene theoretische Tragmodelle her. Mit dieser grundlegenden Arbeit mochte unser Institut einen Beitrag zur Be rechnung solcher Systeme leisten. Vor allem solI sie zur Entwicklung von Be rechnungsverfahren und entsprechenden Normenvorschriften dienen. ZOrich. Mai 1978 Prof. Dr. B. ThOrlimann INHALTSVERZEICHNIS Seite Vorwort 1.

Prepared by the Reinforced Concrete Research Council of ASCE. This report reprints a collection of studies advancing the knowledge of the effects of fatigue loading on the structural behavior of prestressed concrete flexural members. Each study represents one phase of an extensive research program conducted at Lehigh University and sponsored by the Pennsylvania Department of Transportation, the Federal Highway Administration, and the Reinforced Concrete Research Council. The four areas of study are: the effect of stress gradient on the probable fatigue life of plain concrete, as related to the compression block of prestressed concrete flexural members; the probable fatigue life of seven-wire prestressing strand under repeated loading of either constant or varied magnitude; the probable fatigue life of prestressed concrete flexural members, as limited by the fatigue failure of the prestressing strand; and the susceptibility of prestressed concrete flexural members to fatigue failure in shear. This report provides guidance to structural engineers faced with the design or analysis of prestressed concrete flexural members and to research engineers who are seeking to extend the knowledge of structural behavior as affected by repeated loading.

This book was written with a dual purpose, as a reference book for practicing engineers and as a textbook for students of prestressed concrete. It represents the fifth generation of books on this subject written by its author. Significant additions and revisions have been made in this edition. Chapters 2 and 3 contain new material intended to assist the engineer in understanding factors affecting the time-dependent properties of the reinforcement and concrete used in prestressing concrete, as well as to facilitate the evaluation of their effects on prestress loss and deflection. Flexural strength, shear strength, and bond of prestressed concrete members were treated in a single chapter in the of flexural strength has third edition. Now, in the fourth edition, the treatment been expanded, with more emphasis on strain compatibility, and placed in Chapter 5 which is devoted to this subject alone. Chapter 6 of this edition, on flexural-shear strength, torsional strength, and bond of prestressed reinforce ment, was expanded to include discussions of Compression Field Theory and torsion that were not treated in the earlier editions. In similar fashion, expanded discussions of loss of prestress, deflection, and partial prestressing now are presented separately, in Chapter 7. Minor additions and revisions have been made to the material contained in the remaining chapters with the exception of xv xvi I PREFACE Chapter 17. This chapter, which is devoted to construction considerations, has important new material on constructibility and tolerances as related to prestressed concrete.

The design of structures in general, and prestressed concrete structures in particular, requires considerably more information than is contained in building codes. A sound understanding of structural behaviour at all stages of loading is essential. This textbook presents 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 and up-to-date 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. However, where the design requirements are code specific, this book refers to the provisions of Eurocode 2: Design of Concrete Structures and, where possible, the notation is the same as in Eurocode 2. A parallel volume is written to the Australian Standard for Concrete Structures AS3600-2009. The text runs from an introduction to the fundamentals to in-depth treatments of more advanced topics in modern prestressed concrete structures. It suits senior undergraduate and graduate students and also practising engineers who want comprehensive introduction to the design of prestressed concrete structures. It retains the clear and concise explanations and the easy-to-read style of the first edition, but the content has been extensively re-organised and considerably expanded and updated. New chapters cover design procedures, actions and loads; prestressing systems and construction requirements; connections and detailing; and design concepts for prestressed concrete bridges. The topic of serviceability is developed extensively throughout. All the authors have been researching and teaching the behaviour and design of prestressed concrete structures for over thirty-five years and the proposed new edition of the book reflects this wealth of experience. The work has also gained much from Professor Gilbert active and long-time involvement in the development of standards for concrete buildings and concrete bridges.
