FRP Composites for Reinforced and Prestressed Concrete Structures

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.
