内容説明

The in situ rehabilitation or upgrading of reinforced concrete members using bonded steel plates is an effective, convenient, and economic method of improving structural performance. However, disadvantages inherent in the use of steel have stimulated research into using fiber reinforced polymer (FRP) material in its place, with the goal of providing a non-corrosive, more versatile strengthening system. Strengthening of Reinforced Concrete Structures presents a detailed study of the flexural strengthening of reinforced and prestressed concrete members using FRP composite plates. This book covers short and long term performance through model and full-scale experimental testing plus theoretical and numerical considerations. It discusses previous investigative and site work undertaken to strengthen concrete beams using steel bonded pates and the pros and cons of using the steel and composite plate materials. It also presents case histories of construction members upgraded or strengthened using carbon fibre/polymer matrix composite materials bonded to the structural unit. A consortium of academic and industrial researchers provided much of the data and contributed the chapters to this volume. The research and trial tests were undertaken as part of the United Kingdom's ROBUST project. Strengthening of Reinforced Concrete Structures serves to disseminate the large amount of information that resulted from these studies. As detailed in this book, their results will serve to help generate and formulate design specifications as engineers continue to apply these important techniques to an ever-widening range of applications.

内容説明

The in situ rehabilitation or upgrading of reinforced concrete members using bonded steel plates is an effective, convenient and economic method of improving structural performance. However, disadvantages inherent in the use of steel have stimulated research into the possibility of using fibre reinforced polymer (FRP) materials in its place, providing a non-corrosive, more versatile strengthening system. This book presents a detailed study of the flexural strengthening of reinforced and prestressed concrete members using fibre reinforces polymer composite plates. It is based to a large extent on material developed or provided by the consortium which studied the technology of plate bonding to upgrade structural units using carbon fibre / polymer composite materials. The research and trial tests were undertaken as part of the ROBUST project, one of several ventures in the UK Government's DTI-LINK Structural Composites Programme. The book has been designed for practising structural and civil engineers seeking to understand the principles and design technology of plate bonding, and for final year undergraduate and postgraduate engineers studying the principles of highway and bridge engineering and structural engineering.
