000010591 520__ $$2eng$$aTo investigate splitting bond strength for the main steel bars in R/C columns retrofitted with stressed external hoops, a total of 52 sets of main bars are pulled monotonically until failure. Test results indicate that the bond strength becomes higher with the increase in number of external hoops and their initial stress magnitude. This is due to active confining force given by the external hoops, and passive confining forces given by the external hoops and original hoops, in which the passive confinement effect varies depending on the magnitude of active confining force. An equation to express the splitting bond strengths is developed based on the test results of the present study.
