FRP Composites for Reinforced and Prestressed Concrete Structures

Fiber-reinforced polymer (FRP) is a common term used by the civil engineering community for high-strength composites.

Composites have been used by the space and aerospace communities for over six decades and the use of composites by the civil engineering community spans about three decades.

In the composite system, the strength and the stiffness are primarily derived from fibers, and the matrix binds the fibers together to form structural and nonstructural components.

Composites are known for their
high specific strength, high stiffness, and corrosion resistance.

Repair and retrofit are still the predominant areas where FRPs are used in the civil engineering community.

The field is relatively young and, therefore, there is considerable ongoing research in this area.
American Concrete Institute Technical Committee 440 documents are excellent sources
for the latest information.

The primary purpose of this book is to introduce the reader to the basic concepts of repairing and retrofitting reinforced and prestressed concrete structural elements using FRP.

Basic material properties, fabrication techniques, design concepts for strengthening in bending, shear, and confinement, and field evaluation techniques are presented.

The book is geared toward advanced undergraduate and graduate students, professional engineers, field engineers, and user agencies such as various departments of transportation.

A number of flowcharts and design examples are provided to facilitate easy and thorough understanding.

Since this is a very active research field, some of the latest techniques such as near

-surface mounting (NSM) techniques are not covered in this book.

Rather, the aim is to provide the fundamentals and basic information.
