member behavior. In addition, system behavior was investigated analytically using the

test results and confinement model. Finally, an entirely new approach for modeling

confinement was developed.

 This dissertation is organized into nine chapters. In these chapters different

methods by which the CFRP grid can be used to confine concrete are presented. The

methods are presented along with the experimental work and results for each method. A

model based on a new approach that predicts the behavior of unconfined and confined

concrete is also presented.

 Chapter 2 contains a summary of the literature review. Several topics that relate to

this dissertation were explored to find any material that could be helpful in the process of

completing the necessary research.

 In chapter 3 the experimental testing and experimental results from concrete

cylinders that were confined using the CFRP grid are presented. The cylinders were

tested in axial compression.

 In chapter 4 the construction and testing of two reinforced concrete beams using

CFRP grid tubes in the compression zone to confine concrete are described. The

experimental findings from the flexural tests are also presented.

 In chapter 5 and 6 the construction and testing details of FRP reinforced concrete

piles that use the CFRP grid as confinement reinforcement are presented. The

experimental results from the tests are also presented.

 In chapter 7 a static non-linear analysis of pile bents using both prestressing steel

and FRP reinforced piles is discussed. A description of the static non-linear analysis and

the results are presented.
