Incrementaloading-reloading test on a CFRP stranded cable has been conducted under both twist free and twist fixed conditions. The effect on the tensile loading-reloading properties of CFRP cables twist confinement is investigated. The maximum tension capacity under twist free condition is 40% less than that under twist fixed condition. The electrical resistance of strand of CFRP cable along the fiber direction as well as the acoustic emission signals have been monitored during the test. The change of electrical resistance and the AE behavior are strongly correlated each other. It is suggested that the electrical resistance measurement could be effective for detecting of maximum load history of CFRP cable.
