Precast Concrete Structures
Building with precast concrete elements is one of the most innovative forms of construction, This book serves as an introduction to this topic, including examples, and thus supplies all the information necessary for conceptual and detailed design,
Alfred Steinle (1936-2017) turned the lecture notes of Prof, Dr,-Ing, Volker Hahn, which dated from the early 1970s, into a manuscript that became the starting point for this book, After a number of years in bridge-building, Alfred Steinle also became heavily involved in precast concrete construction at Züblin, His theoretical work covered bridge-building with torsion and section deformations in box-girder bridges and in precast concrete structures within the scope of the 6M system with corbels, notched beam ends and pocket foundations, In addition, he was a key figure in many precast concrete projects such as the 6M schools, the University of Riyadh, schools with foamed concrete wall panels in Iraq, Züblin House and the construction of a modern automated precasting plant, Alfred Steinle retired in 1999 and by that time he had risen to the post of authorised signatory in the engineering office at Züblin's head office,
Hubert Bachmann (b, 1959) began his career in a precasting plant in 1976 as an apprentice for concrete and precast concrete construction, After studying structural engineering and completing his doctorate at the University of Karlsruhe, he accepted a post in the structural engineering office of Ed, Züblin AG in Stuttgart in 1993, where he has worked ever since, His duties have included the detailed design of structures of all kinds plus research and development in the civil and structural engineering sectors, He has been presenting the series of Hahn lectures on precast concrete structures at the University of Stuttgart since 2003,
Mathias Tillmann (b, 1970) has been an engineering and standards consultant at Fachvereinigung Deutscher Betonfertigteilbau e,V, (FDB) since 2007 and technical director since 2008, He specialised in structural engineering during his studies at RWTH Aachen University, After attaining his diploma, he worked as a project engineer, structural engineer and designer, Mathias Tillmann has written numerous brochures, advisory documents and specialist articles on the subject of precast concrete,
All three authors have been or still are verymuch involved in construction industry organisations, many technical boards and national and international standards committees concerned with precast concrete construction,
Precast Concrete Structures
This book first appeared as an article written by Alfred Steinle and Volker Hahn for the 1988 edition of the Beton-Kalender. It was reprinted in Beton-Kalender 1995 and then published as a book in the Bauingenieur-Praxis series in 1998. Hubert Bachmann, Alfred Steinle and Volker Hahn updated the information for publication in Beton-Kalender 2009 and this appeared as a new edition of the book in the Bauingenieur-Praxis series in 2010. Alfred Steinle, Hubert Bachmann, and Mathias Tillmann reconceived and completely revised the content for Beton-Kalender 2016, and it is that version that has again been published as a separate book, the third German edition, as part of the Bauingenieur-Praxis BiP series.
The first chapter looks at general aspects of precast concrete construction, its history and the status of European standardisation. The economic use of precast concrete elements is only possible when the design is carried out to suit the production and erection of such elements. Therefore, the second chapter deals with the design of precast concrete structures. Besides outlining the boundary conditions that must be observed when designing for precast concrete, the authors present a number of typical precast concrete designs.
Special attention must be paid to the connections between precast concrete elements, because these are the weak points - for horizontal loads in particular. The stability of precast concrete structures is therefore described in detail in Chapter 3. In particular, owing to the need to check critical details, proper yet simplified engineering assessments are to be preferred to computer calculations when considering stability. Chapters 4 and 5 deal with the various components of precast concrete production and the connections between those components. Specific design issues are examined in detail in Chapter 6.
Façades are becoming an increasingly important application for precast concrete elements. Chapter 7 is therefore dedicated to this topic. And it is façades in particular that are making use of new types of concrete and reinforcement. The final chapter looks at the actual manufacture of precast concrete elements so that the reader gains a full understanding of this form of construction taking into account the needs of production.
New types of concrete, new types of reinforcement, new methods of production - precast concrete construction is the chief proving ground for new developments and applications. Precast concrete therefore represent one of the most innovative forms of construction, a fact that is reflected in its growing popularity.
Although this book focuses on precast concrete from the point of view of the building industry and the authors concentrate mainly on buildings in general, it should not go unmentioned that precast concrete construction has been able to win considerable market shares in many other construction sectors through the development of economic yet bespoke solutions. Examples of these are bridges, tunnel linings, pipes, pipe bridges, towers, masts, piles, detached homes, prefabricated basements, retaining walls, room modules, prefabricated garages, noise barriers, railway sleepers, guided bus tracks, agricultural buildings, ballastless tracks, cooling tower trickle fill structures, etc. The reader is referred to the specialist literature dealing with these specialist areas. This book also only describes structural or architectural precast concrete elements for buildings and structures and not 'concrete products', i.e. small-format components manufactured and stocked in great numbers and available from trade outlets, e.g. sewage pipes, paving stones, etc.
The references at the end of each chapter have been completely recompiled and in the main contain publications of recent years. Older public
