The Florida Department of transportation most commonly uses prestressed concrete piles as foundation in bridges. It has been observed since past few years that the piles installed in aggressive marine environments are subjected to corrosion which generates a need to retrofit them. Although many solutions have been applied to address this issue, these solutions have seem to be ineffective in long term and hence use of advanced materials in piles, to avoid degradation due to corrosion, is necessarry. The ACI and AASHTO equations used to determine the bond properties of a prestressing strand, need to be satisfied by this material, to render this material's suitability as replacement to steel strands. 5--24 in. square prestressed concrete piles which included 3--40 ft. piles and 2--100ft. piles, were cast using 0.6in. diameter carbon fiber composite cables manufactured by Tokyo Rope Mfg. Co. to asses the performance of CFCC as reinforcement. A different anchoring system was used to anchor the CFCC to the abutment in order to prestress the strands. Transfer length was monitored on each pile end and compared to the ACI and AASHTO equations to evaluate the bond characteristics of the CFCC. In addition to that, development length tests and flexural tests were performed at the Marcus. H. Ansley research laboratory to further judge the bond properties of the CFCC with concrete. The results of these tests show if the performance of CFCC is comparable to steel and also describe the technique used to prestress these strands. The 2--100 ft. piles were cast to be driven on site to monitor the static resistance of the piles and would be long term monitored to asses the performance of CFCC against corrosion. / A Thesis submitted to the Department of Civil and Environmental Engineering in partial fulfillment of the requirements for the degree of Master of Science. / Fall Semester, 2013. / Novemeber 6, 2013. / Includes bibliographical references. / Michelle Rambo-Roddenberry, Professor Directing Thesis; Primus Mtenga, Committee Member; Sungmoon Jung, Committee Member; Lisa Spainhour, Committee Member.
