Structural Renovation in Concrete




Preface

In the past few decades, the deterioration of buildings and infrastructures

has been occurring at an ever increasing rate. This has resulted in a worldwide

need for the maintenance, repair and rehabilitation of degraded structures.

To meet the needs, available knowledge and technologies must be collected,

organized and disseminated to engineers and practitioners. Poor

understanding of the deterioration problem and the inability to adopt

proper remediation approaches not only lead to a waste of natural resources,

but also have a negative impact on the economy of the whole world.

The maintenance, repair and rehabilitation of concrete structures involve

several broad issues which encompass technical, social, and economic

aspects, such as the fundamental knowledge of materials and structures as

well as basic understanding of economy and sociology. In this book, we

focus on the technical aspects. From material and structural points of view, a

project for maintenance, repair and rehabilitation of a concrete structure

usually requires knowledge and expertise in the areas of structural materials,

repair materials, structural inspection, material testing, repair and/or

strengthening techniques. To the best of the authors’ knowledge, a book that

systematically covers all these issues is currently not available. The present

book can be considered the first attempt to fill such a void.



The book is divided into six chapters. Chapter 1 gives a brief introduction

to renovation engineering. Chapter 2 explores the causes of deterioration of

concrete structures, covering durability issues and disaster factors. Chapter

3 discusses the techniques of inspection, including destructive and nondestructive

methods. Chapter 4 focuses on the traditional repair and strengthening

methods such as crack repair. Chapter 5 covers the application

of glass fiber reinforced plastics components for bridge deck replacement,

and presents the fundamental mechanics essential for component analysis

and design. Chapter 6 provides updated knowledge on the strengthening

of concrete structures with fiber reinforced polymers.



The book is designed and written primarily to meet the teaching needs for

undergraduate students at senior level and graduate students at entry level.

It can also serve as a reference or a guide for professional engineers in their

practice.
