Abstract
(type = abstract)
Unbonded tendons are being applied more often in the strengthening and rehabilitation of current deteriorated concrete structures. The use of unbonded steel tendons without any protective material presents a higher risk for corrosion. Therefore, unbonded CFRP tendons can be applied in lieu of or in combination with steel tendons due to its high strength and corrosion resistance. This research involves the testing of seven High Performance Concrete (HPC) beams with bonded and unbonded (hybrid) tendons using a combination of steel and CFRP tendons. Several parameters include the area of the unbonded tendons, unbonded tendons material (CFRP or Steel), and depth of unbonded tendons. The experimental testing results in this study includes deflection at mid-span, ultimate load capacity, stress and strain in steel reinforcement, tendons, and concrete, number of cracks, and crack width and spacing for all beams. Finite element analysis for all hybrid beam ultimate strength and deflections are presented and compared to the experimental results. Comparisons of the ultimate stress (fps) in the tendons between the experimental results with three code equations are presented. Test results show that the use of CFRP as an unbonded tendon in hybrid girders can maintain the same ductility level steel tendon can achieve. Additionally, the finite element analysis predicted a similar behavior of concrete beams prestressed with hybrid tendons.
