This paper presents an investigation based on tests results of high-strength concrete (HSC) columns externally confined with post-tensioned steel straps, subjected to monotonic axial load. The parameters of the tests were eccentricity ratio (ei/es = 0, 1), load eccentricity (e = 25 mm, 50 mm), slend...
