Abstract
Previous studies proved that the application of steel-strapping confining technique (SSTT) could significantly remove the undesireable properties of high-strength concrete (HSC) especially the brittleness. However, research studies so far have been concentrated on concentrically loading and neglected the effects of eccentricity on the effectiveness of SSTT-confined HSC columns. In this paper, 3 columns confined with SSTT were tested. These columns were subjected to eccentric loads of 25 mm and 50 mm which simulate moderate eccentricities and high eccentricties loadings, respectively. Results show that the efficiency of SSTT-confinement drops linearly with respect to the increment of eccentricities. An empirical equation was proposed to evaluate the efficiency of SSTT-confinement based on the test results.
